Abstract
A hydrogen bearing silyl carbamate of the general formula: HSiR.sub.n (O.sub.2 CNR'R").sub.3-n is synthesized from hydrogen bearing aminosilane and gaseous carbon dioxide. The resulting hydrogen bearing silyl carbamate is novel in the single hydrogen attached to the silyl carbamate and represents a major new compound for creating novel compositions of matter.
