The Reaction between N,N-Dialkylhydroxylamines and Sulphinyl Chlorides

Banks, Malcolm R.,Hudson, Robert F.

, p. 799 - 800 (2007/10/02)

The reaction of N,N-dialkylhydroxylamines with sulphinyl chlorides proceeds via an O-sulphinylated hydroxylamine intermediate, which has been isolated and characterised by n.m.r. spectroscopy; rearrangement of this intermediate to the sulphonamide has been shown to involve an aminyl radical.
