A slow relaxing species for molecular spin devices: EPR characterization of static and dynamic magnetic properties of a nitronyl nitroxide radical

Nitronyl nitroxides (NitR) are a family of persistent radicals widely used in molecular magnetism and recently suggested as potential candidates for spintronic applications. In this paper we characterize by X-and W-band Electron Paramagnetic Resonance (EPR) spectroscopy the new radical S-4-(nitronyl nitroxide) benzyl ethanethioate (NitSAc) designed for assembling on Au surfaces. We determined the radical magnetic tensors and studied by X-band pulse EPR its spin relaxation behaviour in fluid and glassy solutions of toluene. A comparison with the well known nitroxide 3-carbamoyl-2,2,5,5-tetramethyl-3-pyrrolin-1-oxyl (CTPO) is afforded. The advantages of using NitSAc in technological applications are discussed on the basis of the slow spin relaxation demonstrated by this study.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 54663-78-4, you can contact me at any time and look forward to more communication. Formula: C16H30SSn.

Photocatalytic Conversion of Benzyl Alcohols/Methyl Arenes to Aryl Nitriles via H-Abstraction by Azide Radical

This report presents the visible-light-assisted synthesis of aryl nitriles from easily accessible alcohols or methyl arenes in the presence of O-2. Organic photoredox catalyst, 4CzIPN (1,2,3,5-tetrakis(carbazol-9-yl)-4,6-dicyanobenzene), induces single electron transfer (SET) from azide N(3)(-)and generates azide radical N-3(.).The photogenerated N(3)(.)abstracts H atom from alpha-C-H bond of benzylic system, which provides aldehyde and hydrazoic acid (HN3) in situ. This reaction subsequently forms azido alcohol intermediate that transforms into nitrile with the assistance of triflic acid (Bronsted acid). A range of alcohols and methyl arenes successfully underwent cyanation at room temperature with good to excellent yields and showed good functional group tolerance.

Unexpected facile sequential halolactamization-hydroxylation of 2,3-allenamides with CuX2 for the efficient synthesis of 4-halo-5-hydroxypyrrol-2(5H)-ones

[GRAPHICS] 4-Halo-5-hydroxypyrrol-2(5H)-ones were synthesized from the efficient sequential halolactamization-hydroxylation reaction of 4-monosubstituted 2,3-allenamides with CuX2 (X = Br, CI) in high yields. Halolactamization of fully substituted 2,3-dienamide (1f) afforded 4-halo-pyrrol-2(5H)-ones.

Rotational correlation times of 3-carbamoyl-2,2,5,5-tetramethyl-3-pyrrolin-1-yloxy spin label with respect to heme and nonheme proteins

Noncovalent spin labeled proteins (ovalbumin, bovine serum albumin, hemoglobin, and cytochrome c) were investigated in order to follow the different type of interactions between the nitroxide radical of 3-carbamoyl-2,2,5,5-tetramethyl-3-pyrrolin-1-yloxy spin label and functional groups of heme and nonheme proteins as well as the pH influence on molecular motion of the label with respect to these proteins. EPR spectra were recorded at room temperature and the computer simulation analysis of spectra was made in order to obtain the magnetic parameters. Noncovalent labeling of proteins can give valuable information on the magnetic interaction between the label molecule and the paramagnetic center of the proteins. The relevance of this interaction can be obtained from line shape analysis: computer simulations for nonheme proteins assume a Gaussian line shape, whereas for heme proteins, a weighted sum of Lorentzian and Gaussian components is assumed. In the framework of the moderate jump diffusion model for rotational diffusion, the rotational correlation time is strongly influenced by pH, because of the electrostatic interactions and hydrogen bonding.

Evaluation of pyrrolin-2-one derivatives synthesized by a new practical method as inhibitors of plasminogen activator inhibitor-1 (PAI-1)

We describe in this Letter a new synthetic method for pyrrolin-2-ones as potent plasminogen activator inhibitor-1 (PAI-1) inhibitors. Pyrrolin-2-one derivatives synthesized from N-2-oxoethylamides and aldehydes in aqueous NaOH by one-pot were evaluated for their PAI-1 inhibitory activity. Among these derivatives, compounds 16 and 18 were found to possess potent PAI-1 inhibitory activity (compound 16: IC(50): 0.69 mu M, compound 18: IC(50): 0.65 mu M). (C) 2009 Elsevier Ltd.

Detection of CH3C3N in Titan’s Atmosphere

Titan harbors a dense, organic-rich atmosphere primarily composed of N-2 and CH4, with lesser amounts of hydrocarbons and nitrogen-bearing species. As a result of high-sensitivity observations by the Atacama Large Millimeter/submillimeter Array (ALMA) in Band 6 (similar to 230-272 GHz), we obtained the first spectroscopic detection of CH3C3N (methylcyanoacetylene or cyanopropyne) in Titan’s atmosphere through the observation of seven transitions in the J = 64 -> 63 and J = 62 -> 61 rotational bands. The presence of CH3C3N on Titan was suggested by the Cassini Ion and Neutral Mass Spectrometer detection of its protonated form: C4H3NH+, but the atmospheric abundance of the associated (deprotonated) neutral product is not well constrained due to the lack of appropriate laboratory reaction data. Here, we derive the column density of CH3C3N to be (3.8-5.7).x.10(12) cm(-2) based on radiative transfer models sensitive to altitudes above 400 km Titan’s middle atmosphere. When compared with laboratory and photochemical model results, the detection of methylcyanoacetylene provides important constraints for the determination of the associated production pathways (such as those involving CN, CCN, and hydrocarbons), and reaction rate coefficients. These results also further demonstrate the importance of ALMA and (sub)millimeter spectroscopy for future investigations of Titan’s organic inventory and atmospheric chemistry, as CH3C3N marks the heaviest polar molecule detected spectroscopically in Titan’s atmosphere to date.

New applications of N-acyliminium precursors: Tetracarbonyliron-mediated stereoselective alkylations of 5-(R)-isopropoxy-3-pyrrolin-2-ones

Lewis acid catalyzed allylic substitutions with several nucleophiles at C-5 of the cis-tetracarbonyliron complexes of N-acetyl- and N-tosyl-5-(R) -isopropoxy-3-pyrrolin-2-ones occur highly regio- and stereoselectively. The results are interpreted as being indicative of the intermediacy of a ( pi-allyl)tetracarbonyliron cation, with possible preceding formation of an N-acyl- or an N-tosyliminium ion.
