REACTION OF TRIALKYL PHOSPHITES AND a-HALOKETONES IN APROTIC MEDIA (PERKOW-ARBUZOV REACTION) AND IN PROTIC SOLVENTS

Abstract

The authors suggest a new reaction mechanism for the Perkow-Arbuzov reaction yielding vinyl phosphates and B-keto phosphonates. For the reaction of a-haloacetophenones and trialkyl phosphites in alcohol or acetic acid giving 3 products a uniform mechanism involving again a common intermediate was assumed. In the course of our work the applicability of Hammett's equation has been extended for studying parallel and braching reactions, as well.
