THE PREPARATION OF DIMETHYL PHOSPHOROCHLORIDITE AND ITS HOMOLOGS FROM TRIALKYL PHOSPHITES AND DICHLOROTRIPHENYLPHOSPHORANE

Abstract

A novel convenient synthesis of dialkyl phosphorochloridites based on the reaction of trialkyl phosphites with dichlorotriphenylphosphorane has been described. In this way the commonly used dialkyl phosphorochloridites (3a–e) were prepared in satisfactory yields. Their identity was confirmed by ³¹P-NMR spectroscopy as well as by their refractive index.
