Formation of arsinimines by reactions of triphenylarsine with compounds generally believed to be nitrene precursors
Abstract
The little known triphenylarsinimines (Ph3-As = NX, where X = C6F5, 4-6-dimethylpyrimidyl, EtO2C, p-Me·C6H4·SO2, MeSO2, CN, Bz, p-NO2·C6H4·CO) are prepared either by reaction of triphenylarsine under nitrene-producing conditions with azides (XN3), 3-aryl-1,4,2-dioxazolidin-5-ones, N-p-nitrobenzenesulphonoxy-urethane and toluene-p-sulphonamide, and/or by a non-nitrene route from triphenylarsine, lead tetra-acetate, and amides via triphenylarsine diacetate, Ph3As(OAc)2, now isolated.
