A new Ni(dmit)(2)-based organic magnetic charge-transfer salt, (m-PO-CONH-N-methylpyridinium) [Ni(dmit)(2)]center dot CH3CN

A new Ni(dmit)(2)-based organic magnetic charge-transfer (CT) salt, (m-PO-CONH-N-methylpyridinium)[Ni(dmit)(2)]center dot CH3CN, where PO = 2,2,5,5-Tetramethyl-3-pyrrolin-1-oxyl free radical and dmit = 2-Thioxo-1,3-dithiole- 4,5-dithiolate, was obtained, the crystal structure and magnetic properties of which are reported. Magnetic susceptibility of the CT salt obeys a combination of 1D ferromagnetic (1DF) Heisenberg (J(1DF) = +0.26 K) and Singlet-Triplet (ST) models (J(ST) = -51.2 K) with mean field (MF) approximation (J(MF) = -6.7 K), suggesting that spins on the PO radicals form 1D ferromagnetic chains and spins on the Ni (dmit)(2) monoanions form spin dimers at low temperature, the latter of which was also confirmed by band calculations.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 591-50-4, in my other articles.

On the methylacetylene abundance and nitrogen isotope ratio in Pluto’s atmosphere

To bring our photochemical model of Pluto’s atmosphere and ionosphere (Krasnopolsky, 2020) into agreement with the recent detection of 5 x 10(15) cm(-2) methylacetylene C3H4 (Steffl et al., 2020), rate coefficients of the three key reactions of C3H4 production and loss have been changed to values calculated by (2019). This change reduces the abundance of cyanoacetylene HC3N close to the measured ALMA upper limit (Lellouch et al., 2017), increases the model abundances of H-2 and C3H8 by factors of 1.3, and reduces the abundances of H and C4H2 by factors of 1.3, while other species are changed less than 5% in the model. The predicted abundance of atomic hydrogen agrees with that derived from the observed Lyman-beta emission by Steffl et al. (2020). The observed (HCN)-N-14/(HCN)-N-15 > 125 on Pluto (Lellouch et al., 2017) looks puzzling compared to (HCN)-N-14/(HCN)-N-15 = 60 on Titan. Our analysis confirms the predissociation of N 2 at 80-100 nm as the main process of nitrogen isotope fractionation. The observed twofold difference is partially caused by the diffusive depletion of the heavy isotope in HCN and in the predissociation of N-2. On Pluto, the mean altitudes of HCN and predissociation of N-2 are 500 and 860 km, well above the homopause at 96 km. On Titan, observations of (HCN)-N-14/(HCN)-N-15 refer to 90-460 km (Vinatier et al., 2007), the predissociation occurs near 985 km, both below the homopause at 1000 km, and diffusive depletion does not occur. Therefore the observed limit corresponds to N-14/(15) N > 253 for N-2 in the lower atmosphere and N-14/N-15 > 228 in the upper layers of the N-2 ice. These limits reflect the conditions on Pluto in the last two million years, which is the lifetime of N-2 in Pluto’s atmosphere with the current N-2 loss of 37.5 g cm(-2) Byr(-1) primarily for photodestruction. The calculated isotope fractionation factor of 1.96 accounts for the formation and condensation of nitriles, diffusive separation, and fractionation in thermal escape. Variations of N-14/N-15 in the N-2 ice are related to the evolution of the solar EUV, mixing processes in the N-2 ice, and possible periods of hydrodynamic escape, which are poorly known and not considered here.

A catalyst-free and recycle-reinforcing elastomer vitrimer with exchangeable links

Vitrimers, as intriguing polymers, possess exchangeable links in the crosslinking networks, endowing them with the abilities of recycling and reprocessing. However, most of vitrimers are generally fabricated via complex synthesis and polymerization processes. Toxic and unstable exogenous catalysts are inevitably applied to activate the exchange reaction to rearrange the crosslinking networks. These drawbacks limit the widespread applications of vitrimers. Moreover, most reported vitrimers could only partially maintain or severely deteriorate their mechanical properties after recycling. Herein, to solve the above-mentioned problems, for the first time, a catalyst-free and recycle-reinforcing elastomer vitrimer is revealed. By the reactive blending of commercially available epoxidized natural rubber and carboxylated nitrile rubber, the elastomer vitrimer associated with exchangeable beta-hydroxyl ester bonds was obtained. Strikingly, the vitrimer exhibits an exceptional recycle-reinforcing property. This work provides a feasible method to fabricate elastomer vitrimers, which promotes the recycling of crosslinking commercial available elastomers.

De Novo Synthesis of 3-Pyrrolin-2-Ones

This review presents a systematic survey of the literature (through the end of 2014) for de novo syntheses of 3-pyrrolin-2-ones from acyclic precursors or via transformation of other cyclic systems such as pyrroles, pyrrolidinone, and maleimides. One-component intramolecular cyclization approaches, two-component intermolecular cyclization approaches, and multicomponent intermolecular cyclization approaches are treated separately and organized based on the location(s) of the new bonds that are formed in the construction of the 3-pyrrolin-2-one ring system. 3-Pyrrolin-2-ones make important synthetic targets due to their occurrence in natural products, their diverse biological activity, and their utility as building blocks for the preparation of other materials.

SYNTHESIS OF NITROXIDE CONTAINING POLYENES – 2 CHEMICALLY-MODIFIED RETINALS AND THEIR INTERACTION WITH BACTERIORHODOPSIN

The synthesis and spectroscopic characterization of two retinal analogues is described, the paramagnetic 3-pyrrolin-1-yloxy analogue 1 and its diamagnetic equivalent, the 3-pyrroline analogue 2. Various aspects of the synthesis of the aminoxy group containing polyenes are discussed. Upon interaction with bacterioopsin, both 1 and 2 are incorporated in the protein and form a system with lambda(max) 459 nm. Neither of the two bacteriorhodopsin analogues is photoactive. ESR spectroscopy data of the system containing 1 show that the ring part of the chromophore in the protein is rigidly fixed in orientation.

Enantioselective Cyanoborylation of Allenes by N-Heterocyclic Carbene-Copper Catalysts

The simultaneous incorporation of both a cyano group and a boryl unit into the C=C double bonds of allenes in a regio- and stereoselective fashion is of much interest and importance but remains a significant challenge. We report herein a copper-catalyzed chemo-, regio-, and enantioselective cyanoborylation of allenes, which afforded a family of valuable enantiopure beta-boryl allyl nitriles. The high enantioselectivity was achieved by installing of appropriate substituents at the C2 and C6 positions of the naphthyl groups in our newly synthesized N-heterocyclic carbene (NHC) ligands. The reaction mechanism has been clarified by some stoichiometric reactions and computational studies. This work provides an inspiring example of the development of selective catalytic reactions for the synthesis of functional molecules through fine-tuning the ligands in catalysis.
