The title compound, C44H35N4O3 center dot 2.5C(6)H(6) (1), consists of a terpyridine and a N-oxylpyrroline-3-formate group separated by an aromatic spacer, viz. 4-(phenylethynyl)-1,1′-biphenyl. It crystallized in the triclinic space group P (1) over bar with two and a half benzene solvate molecules (one benzene molecule is located about an inversion center), while the dichloromethane solvate (2) of the same molecule [Ackermann et al. (2015). Chem. Commun. 51, 5257-5260] crystallized in the tetragonal space group P4(2)/n, with considerable disorder in the molecule. In (1), the terpyridine (terpy) group assumes an all-trans conformation typical for terpyridines. It is essentially planar with the two outer pyridine rings (B and C) inclined to the central pyridine ring (A) by 8.70 (15) and 14.55 (14)degrees, respectively. The planes of the aromatic spacer (D, E and F) are nearly coplanar with dihedral angles D/E, D/F and E/F being 3.42 (15), 5.80 (15) and 4.00 (16)degrees, respectively. It is twisted with respect to the terpy group with, for example, dihedral angle A/D being 24.48 (14)degrees. The mean plane of the N-oxylpyrroline is almost normal to the biphenyl ring F, making a dihedral angle of 86.57 (16)degrees, and it is inclined to pyridine ring A by 72.61 (15)degrees. The intramolecular separation between the O atom of the nitroxyl group and the N atom of the central pyridine ring of the terpyridine group is 25.044 (3) angstrom. In the crystal, molecules are linked by pairs of C-H center dot center dot center dot O hydrogen bonds, forming inversion dimers. The dimers stack along the c axis forming columns. Within and between the columns, the spaces are occupied by benzene molecules. The shortest oxygen-oxygen separation between nitroxyl groups is 4.004 (4) angstrom. The details of the title compound are compared with those of the dichloromethane solvate (2) and with the structure of a related molecule, 4′-{4-[(2,2,5,5-tetramethyl-N-oxyl-3-pyrrolin-3-yl)ethynyl]phenyl}-2,2′:6’,2 ”-terpyridine (3), which has an ethynylphenyl spacer [Meyer et al.

Sodium as High-efficient Catalyst in Hydroboration of Unsaturated Compounds

The catalysts used to catalyze the hydroboration of nitriles or carbodiimides usually have some disadvantages such as complex structure, high cost, large pollution of environment and so on. It is an important development direction to use the main group metals instead of the transition metals to reduce the costs and realize green catalysis. In this paper, using NaH or NaOH as a catalyst, an efficient reaction of nitrile or carbodiimide with pinacol borane (HBPin) has been achieved. It was found that 3.5 mol% of NaH participated in the hydroboration reaction in a simple and effective method under slight solvent-free circumstances. In addition, intermolecular chemoselectivity hydroboration of nitrile and substrates with different functional groups was also investigated by employing three different catalysts. This reaction uses the inorganic alkali with simple structure, commercially available and low cost to synthesize organoborane compounds, which provides ideas for industrial development.

Studies on the pyrrolinone metabolites derived from the tobacco alkaloid 1-methyl-2-(3-pyridinyl)pyrrole (beta-nicotyrine)

Previous studies have established that the tobacco alkaloid 1-methyl-2-(3-pyridyl)pyrrole (beta-nicotyrine) is biotransformed by rabbit lung and liver microsomal preparations to an equilibrium mixture of the corresponding 3- and 4-pyrrolin-2-ones. Autoxidation of these pyrrolin-2-ones generates the chemically stable 5-hydroxy-5-(3-pyridinyl)-3-pyrrolin-2-one. This paper summarizes efforts to document more completely the pathway leading to this hydroxy-pyrrolinone. Chemical and spectroscopic evidence implicates the 2-hydroxy-1-methyl-5-(3-pyridinyl)pyrrole (2-hydroxy-beta-nicotyrine) as the key intermediate in this reaction pathway. Of potential toxicological interest is the detection of radical species derived from the autoxidation of this compound.

EFFECTS OF MYOSMINE ON ANTIOXIDATIVE DEFENCE IN RAT LIVER

Myosmine [3-(1-pyrrolin-2-yl) pyridine] is an alkaloid structurally similar to nicotine, which is known to induce oxidative stress. In this study we investigated the effects of myosmine on enzymatic and nonenzymatic antioxidative defence in rat liver. Wistar rats received a single i.p. injection of 19 mg kg(-1) of myosmine and an oral dose of 190 mg kg(-1) by gavage. Nicotine was used as a positive control. Through either route of administration, myosmine altered the hepatic function by decreasing the levels of reduced glutathione, superoxide dismutase, and glutathione peroxidase activities on one hand and by increasing malondialdehyde, catalase, and glutathione reductase activity on the other. Compared to control, both routes caused significant lipid peroxidation in the liver and altered hepatic enzymatic and non-enzymatic antioxidative defences. The pro-oxidant effects of myosmine were comparable with those of nicotine.

Free radical generation induced by ultrasound in red wine and model wine: An EPR spin-trapping study

Direct evidence for the formation of 1-hydroxylethyl radicals by ultrasound in red wine and air-saturated model wine is presented in this paper. Free radicals are thought to be the key intermediates in the ultrasound processing of wine, but their nature has not been established yet. Electron paramagnetic resonance (EPR) spin trapping with 5,5-dimethyl-l-pyrrolin N-oxide (DMPO) was used for the detection of hydroxyl free radicals and 1-hydroxylethyl free radicals. Spin adducts of hydroxyl free radicals were detected in DMPO aqueous solution after sonication while 1-hydroxylethyl free radical adducts were observed in ultrasound-processed red wine and model wine. The latter radical arose from ethanol oxidation via the hydroxyl radical generated by ultrasound in water, thus providing the first direct evidence of the formation of 1-hydroxylethyl free radical in red wine exposed to ultrasound. Finally, the effects of ultrasound frequency, ultrasound power, temperature and ultrasound exposure time were assessed on the intensity of 1-hydroxylethyl radical spin adducts in model wine.

Relationship between electron difference density distribution, planarity of the >N-O groups and intermolecular hydrogen bond systems in crystals of stable nitroxide radicals

The electron density distribution calculated for 2,2,6,6-tetramethyl-1-piperidinyloxy (1), 4-hydroxy-2,2,6,6-tetramethyl-1-piperidinyloxy (2) and 3-carbamoyl-2,2,5,5-tetramethyl-3-pyrrolin-1-yloxy (3) free radicals on the basis of low-temperature X-ray single crystal diffraction experiments revealed some differences in region of the > N-O,groups. Generally, the experimental bonding density along the axis of the N-O bond is relatively low and asymmetric in cases of the pyramidal geometry of the aminoxyl group (1 and 2) and almost symmetrical for the planar geometry (3). The shape and distribution of electron densities in the region of the oxygen lone-pairs suggest that this atom is sp(3) hybridized but the spatial orientation of these maxima depends on hydrogen bond interactions (> N-O … H) in studied crystals. Also the relation between the direction of the relatively strong hydrogen bonds (O … H < 2.2 Angstrom) and the geometry of aminoxyl groups analysed for crystal structures collected in the Cambridge Structural Database showed that these interactions can affect the aminoxyl group geometry.

Understanding the Mechanism between Antisolvent Dripping and Additive Doping Strategies on the Passivation Effects in Perovskite Solar Cells

Perovskite polycrystalline films contain numerous intrinsic and interfacial defects ascribed to the solution preparation process, which are harmful to both the photovoltaic performance and the stability of perovskite solar cells (PVSCs). Although various passivators have been proved to be promising materials for passivating perovskite films, there is still a lack of deeper understanding of the effectiveness of the different passivation methods. Here, the mechanism between antisolvent dripping and additive doping strategies on the passivation effects in PVSCs is systematically investigated with a nonfullerene small molecule (F8IC). Such a passivated effect of F8IC is realized via coordination interactions between the carbonyl (C=O) and nitrile (C-N) groups of F8IC with Pb2+ ion of MAPbI(3). Interestingly, F8IC antisolvent dripping can effectively passivate the surface defects and thus inhibit the nonradiative charge recombination on the upper part of the perovskite layer, whereas F8IC additive doping significantly reduces the surface and bulk defects and produces a compact perovskite film with denser crystal grains, thus facilitating charge transmission and extraction. Therefore, these benefits are translated into significant improvements in the short-circuit current density (J(sc)) to 21.86 mA cm(-2) and a champion power conversion efficiency of 18.40%. The selection of an optimal passivation strategy should also be considered according to the energy level matching between the passivators and the perovskite. The large energetic disparity is unsuitable for additive doping, whereas it is expected in antisolvent dripping.

Intermolecularly hydrogen-bonded dimeric helices: tripyrrindiones

A rare and unusual class of tripyrrolic compounds, violet-colored tripyrrin-1,14-diones, can be prepared easily and in moderately high yields from base (piperidine)-catalyzed condensation of 3-pyrrolin-2-ones with 2,5-diformylpyrroles. Dipyrrinones adopt the all-syn-Z conformation leading to helical, lock-washer like structures, which form dimers that are held together by intermolecular hydrogen bonds in nonpolar solvents and in the crystal. Strong bathochromic spectral shifts of the tripyrrindione similar to 480 nm long wavelength UV-visible absorption band are seen with added base: DBU, 615 nm; TFA, 573 nm; and Zn(OAc)(2), 586 nm.
