Reactions of the silicon–phosphorus bond. Part II. Fissions of trimethylsilyldiphenylphosphine by halogens and halides

Abstract

The action of a wide variety of nonmetal and metal halides upon trimethylsilyldiphenylphosphine has been studied. Halogens cause fission of the silicon–phosphorus bond to produce the corresponding organo-phosphorus and silicon halides. Other reactions with nonmetal halides produced diphenylborondiphenylphosphide, tetraphenyldiphosphorus, and tetramethyldiarsine. The fission by copper, nickel, and palladium halides produced diphenylphosphido-conplexes of these elements which appear to be oligomeric or polymeric, but the nature of these compounds merits further study. Many metal halides were reduced to metal with concomitant formation of tetraphenyldiphosphine.
