A General Method for the Synthesis of Te-Aryl Phosphorotellurate Triesters

Abstract

A general and practical method for the synthesis of Te-aryl phosphorotellurates is described. A series of Te-aryl phosphorotellurates could be synthesized in good to excellent yields by the reaction of dialkyl, diaryl and trialkyl phosphites with arenetellurynyl and arenetellurenyl halides. A phenylphosphonotelluroate and a phosphorotelluramidate were also prepared by a similar procedure.

Key words

phosphorus - phosphorotellurates - tellurium
