Formation of isomeric diphenyl pentaerythrityl diphosphites in transesterification of triphenyl phosphite with pentaerythritol

Abstract

Employing the method of thin-layer chromatography, it was shown that the transesterification of triphenyl phosphite with pentaerythritol gives a mixture of two isomeric diphenyl pentaerythrityl diphosphites, the structure of which was confirmed by synthesis. © 1973 Consultants Bureau.
