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.
