The Stepwise Alkoxylation of Phenyl Phosphorodichloridate

Abstract

Abstract The reaction of phenylphosphorodichloridate (P.P.D.C.) with various alcohols in the presence of a tertiary base has been studied. With equimolar proportions of the P.P.D.C. and the requisite alcohol in light petroleum, the following compounds have been obtained: phenyl n-undecyl, phenyl n-butyl and phenyl methyl hydrogen phosphates. When two molar proportions of the alcohol in acetonitrile are added to P.P.D.C., phenyl bis-n-undecyl, phenyl bis-n-butyl and phenyl bis-n-amyl phosphates may be isolated. By hydrogenolysis (of the phenyl group diundecyl, dibutyl, and dimethyl hydrogen phosphates result.
