Grignard reaction of substituted nitromethanes: The nwe observations
Reactions of 1-(1-nitromethyl)cyclohexene and its derivatives with excess of methylmagnesium iodide have been studied.In a few cases a chemoselective attack on the nitro group by the Grignard reagent has been observed.The N,N-dialkylhydroxylamine, the nor

Reduction of Allylic Nitro Compounds to Oximes with Carbon Disulfide under Solid-Liquid Phase-Transfer Catalysis Conditions
A mild procedure for the synthesis of allylic oximes 2 from the corresponding nitro derivatives 1, using carbon disulfide as reducting agent in the presence of wet potassium carbonate and a catalytic amount of a phase-transfer agent, is described.

One-pot Conversion of Allylic Nitro Compounds Into Nitriles with Carbon Disulphide under Phase-transfer Catalysis Conditions
An one-pot synthesis of allylic nitriles 3 from the corresponding nitro derivatives 1 is described.In the first step the substrates 1 are reduced to the oximes 2 by carbon disulphide in the presence of wet potassium carbonate, in solid-liquid PTC conditions.In the second, the formed oximes 2 are dehydrated by adding more CS2 and 15percent aqueous NaOH.
