We report herein a highly efficient palladium-catalyzed carbene insertion into strained Si-C bonds of benzosilacyclobutanes, which provides an efficient method to access α-chiral silanes. With a sterically hindered ligand, carbene insertion into the C(sp3 )-Si bond of benzosilacyclobutanes occurred in excellent site- and enantioselectivity, while C(sp2 )-Si bond insertion occurred selectively with
