Rh(I)-Catalyzed Silylation of Aryl and Alkenyl Cyanides Involving the Cleavage of C-C and Si-Si Bonds

摘要

The cleavage of C-C sigma bonds by transition-metal complexes represents a fundamental challenge in the field of organometallic chemistry.Success has primarily been limited to systems that rely on relatively specific driving forces,such as relief of ring strain and aromatization or on chelation assistance.
