The origin of the amide formed in the photochemical reactions of aminimides: rearrangement of trimethylammonio-N-diphenylphosphinoylimide to N-(dimethylaminomethyl)diphenylphosphinic amide
Abstract
The principal photochemical reaction of Ph2P(O)–NMe3 in dimethyl sulphoxide or methanol is rearrangement to Ph2P(O)NHCH2NMe2 which subsequently decomposes to give the amide Ph2P(O)NH2; rearrangement also occurs with PhCO–NMe3but is apparently not the major reaction pathway
