Aminosilylation of heterocumulenes and the intramolecular decomposition of their silyl-functionalized adducts

Article abstract of DOI:10.1016/0022-328X(91)86160-R

Heteroorganic amidosilanes are readily obtained by interaction of CO2, CS2 and other heterocumulenes with pentacoordinated diaminosilanes.A comparison is made with the corresponding reactions of tetracoordinated species.Decompositon of these bifunctional organosilanes gives 2-substituted ureido derivatives and base-stabilized low coordinated silicon species, seemingly by a unimolecular thermal β-elimination.
