Abstract

We report a method to construct chiral tetraorganosilicons by tandem silacyclobutane (SCB) desymmetrization-dehydrogenative silylations. A wide array of dibenzosiloles with stereogenic quaternary silicon centers were obtained in good yields and enantioselectivities up to 93 % ee. Chiral TMS-segphos was found to be a superior ligand in terms of reactivity and enantioselectivity.
