Reactions of carbonyl compounds with tervalent phosporus reagents. Part 8. Acetyldiphenylphosphine oxide

Abstract

Detailed spectra are described for acetyldiphenylphosphine oxide (1), prepared as a crystalline solid from acetyl chloride and methyl diphenylphosphinite. The oxide (1) is a potent acylating agent and readily undergoes carbonyl addition reactions. Acetoxydiphenylphosphine and (1) interconvert spontaneously, and then slowly form a dimer.
