Preparation of diphenyl phosphide and substituted phosphines using alkali metal in silica gel (M-SG)

Nandi, Partha,Dye, James L.,Bentley, Philip,Jackson, James E.

, p. 1688 - 1692 (2009)

Alkali metals absorbed in silica gel (the M-SG reagents) efficiently cleave C-P bonds in triaryl- and diarylphosphines. The resulting alkali metal phosphides can serve as useful building blocks for a variety of phosphines. Alkyldiarylphosphines undergo exclusive aryl group cleavage.
