Claims20
A compound comprising a bis(silyl)phosphide and a cation wherein the silyl is HnSiX3-n where X is a halogen, alkoxy, aryloxy, amido or arylamido and n is 0, 1, 2 or 3.
A method of preparing a bis(silyl)phosphide comprising contacting a phosphate-source with a silane reducing agent wherein the silyl is HnSiX4-n where X is a halogen, alkoxy, aryloxy, amido or arylamido and n is 1, 2 or 3.
A method of preparing a phosphorus chemical comprising contacting a bis(silyl)phosphide with an electrophilic reagent to form the phosphorus chemical wherein the silyl is HnSiX3-n where X is a halogen, alkoxy, aryloxy, amido or arylamido and n is 0, 1, 2 or 3.
