Abstract

Arylnitromethanes were prepared by oxidation of aldoximes with sodium perborate or with urea hydrogen peroxide in the presence of boric acid. The use of urea hydrogen peroxide complex provides better and more stable yields of nitro compound and allows one to halve an acetic acid consumption. Only E-aldoximes are oxidized to arylnitromethanes while Z-isomers are transformed into complex mixtures not containing arylnitromethanes.
