摘要

N-Phosphinoylhydroxylamines are the phosphorus analogues of hydroxamic acids, and the 0-sulfonyl derivatives 1 (R = phenyl or alkyl) undergo a Lossen-like rearrangement with base (Scheme 1).1 This involves migration of a phenyl group from phosphorus to nitrogen, and gives rise to a phosphon- amide product such as 3. The monomeric metaphosphonimi- date 2 is a plausible intermediate, being analogous to the isocyanate formed in a Lossen ...
