A range of nitro compounds are smoothly reduced to their corresponding oximes under the synergistic effects of visible light irradiation, the Ru(bpy)3Cl2 photocatalyst, Hünig's base, Mg(ClO 4)2 activation, and MeCN solvent. This remarkably mild and environmentally benign protocol, when orchestrated with classical Beckmann rearrangement, enables such high-value industrial feedstock as caprolactam to be readily accessed from simple precursor nitrocyclohexane.

Chemoselective transfer hydrogenation of conjugated nitroalkenes catalyzed by [RhCl2Cp·]2-diamine complex (Cp ·=η5-C5Me5) using HCOOH/Et3N (5:2) (TEAF) as a hydrogen source was realized. A variety of nitrostyrenes, β-methyl nitrostyrenes, and 3-methyl-4-nitro-5-alkenyl- isoxazoles were reduced smoothly in good to excellent yields in short reaction time. Other functional groups are inert under the reaction conditions.

Photoscissors: Structurally variable and synthetically robust iminium ions and amino radicals species could be simultaneously generated by visible-light-promoted photoredox cleavage of the C-C bonds in simple vicinal diamine precursors under very mild reaction conditions. Copyright

β-Phenyl-β-hydroxynitroethanes having activating aryl substituents are treated with triethylsilane/trifluoroacetic acid under solventless conditions to give the corresponding phenylnitroethanes. Substrates having no aryl substituents or substituents that
A Highly Chemoselective Reduction of Conjugated Nitro Olefins with Hantzsch Ester in the Presence of Silica Gel
FUJI, Masayuki
, p. 4029 - 4036 (2007/10/02)
An effective system to reduce conjugated nitro olefins into the corresponding nitroalkanes is described.The system composed Hantzsch ester (HEH) and silica gel in benzene exerts high yield and excellent chemoselectivity under almost neutral conditions.Facile applications of the system to the syntheses of natural products are also described.
