Preparation of N-(diphenylphosphinyl)hydroxylamine and lossen-like rearrangement of its O-methanesulphonate
Abstract
N-(Diphenylphosphinyl)hydroxylamine (4a) can be prepared from diphenylphosphinic chloride using O-trimethylsilylhydroxylamine; it forms O-acetyl (5a) and O-methanesulphonyl (6a) derivatives, the latter undergoing Lossen-like rearrangement in t-butylamine.
