In the structure of the 1:1 proton-transfer compound of isopropyl-amine with 4,5-dichloro-phthalic acid, C(3)H(10)N(+)·C(8)H(3)Cl(2)O(4) (-), the three cation H-atom donors associate with three separate carboxyl O-atom anion acceptors, giving conjoint cyclic R(4) (4)(12), R(4) (4)(16) hydrogen-bonding cation-anion inter-actions in a one-dimensional ribbon structure. In the anions, the carboxyl ...

Photochemical transformations were investigated for monomers of 7-azaindole isolated in low-temperature Ar and normal-H2 (n-H2) matrices. The most stable N1H tautomer was the only form of the compound populated in Ar and n-H2 matrices before any irradiation. Upon exposure of Ar matrices to UV (λ > 270 nm) light, two higher-energy tautomers N7H and C3H were photoproduced. Additionally, spectral ...

in atom transfer radical polymerization (atrp) of methyl acrylate (ma) with polyvinyl acetate macroinitiator in bulk at 90°c the plots of ln [m]0/[m] increased linearly with reaction time. the apparent propagation rate constant (kp app) of the reaction was obtained from the linear curve and used to calculate the free macroradical concentration ([r°]) in polymerization medium. the [r°] and also ...

[email protected] Abstract PhnJ from the C–P lyase complex catalyzes the cleavage of the carbon–phosphorus bond in ribose-1phosphonate-5-phosphate (PRPn) to produce methane and ribose-1,2-cyclic-phosphate-5-phosphate (PRcP). This protein is a novel radical SAM enzyme that uses glycyl and thiyl ra...

Two isomers, [Ru(1)]2+ (Ru = Ru(bpy)2, bpy = 2,2'-bipyridine, 1 = 2-(pyrid-2'-yl)-1-azaacridine) and [Ru(2)]2+ (2 = 3-(pyrid-2'-yl)-4-azaacridine), are bioinspired model compounds containing the nicotinamide functionality and can serve as precursors for the photogeneration of C-H hydrides for studying reactions pertinent to the photochemical reduction of metal-C1 complexes and/or carbon dioxide...
