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
