Process for preparation of alkenylphosphine oxides or alkenylphosphinic esters

摘要

A novel process for preparation of alkenylphosphine oxides or alkenylphosphinic acid esters provided by which the objective compounds can be easily, safely and efficiently synthesized and easily separated and purified with little formation of by-products. Specifically, a process of conducting the addition reaction of an easily available secondary phosphine oxide or hydrogen phosphinic acid ester with an acetylene compound with a catalyst containing a Group 9 or 10 metal of the periodic table to thereby obtain the corresponding alkenylphosphine oxide or alkenylphosphinic acid ester.
