Abstract
A process for the manufacture of phosphorus (I) species, phosphorus (III) species, and lower hydrides of phosphorus from phosphorus (V) species is provided. Particularly, the present invention is directed to a process for the preparation of P(I) species, P(III) species, and lower hydrides of phosphorus, wherein the process comprises contacting a P(V) species with a reducing agent in the presence of a catalyst effective to promote reduction of the P(V) species by reaction with a reducing agent. Preferably the reducing agent comprises hydrogen.
Claims36
A process for the preparation of a P(I) species, said process comprising contacting a P(V) species with a reducing agent in the presence of a reducing catalyst for the reduction of said P(V) species.
A process for the preparation of a P(III) species, said process comprising contacting a P(V) species with hydrogen gas in the presence of a reducing catalyst for the reduction of said P(V) species.
A process for the preparation of a mixture comprising a P(I) species and a P(III) species, said process comprising contacting a P(V) species with hydrogen gas in the presence of a reducing catalyst for the reduction of said P(V) species.
A process for the preparation of a lower hydrides of phosphorus, said process comprising contacting a P(V) species with hydrogen gas in the presence of a reducing catalyst for the reduction of said P(V) species.
