REACTION OF SECONDARY PHOSPHINES WITH CARBON TETRACHLORIDE. SYNTHESIS OF ALKYLACYLCHLOROPHOSPHINES

Veits, Yu. A.,Neganova, E. G.,Filippov, M. V.,Borisenko, A. A.,Foss, V. L.

, p. 114 - 118 (2007/10/02)

We present a method for the synthesis of hitherto unknown chlorides of alyklacylphosphinic acids by reaction of alkylacylphosphines with carbon tetrachloride in the presence of triethylamine.We have discovered a reaction of chlorides of alkylacylphosphinic acids in which intermolecular migration of an acyl group takes place.
