Multifunctional P-ligand-controlled “silicon-centered” selectivity in Rh/Cu-catalyzed Si–C bond cleavage of silacyclobutanes

Abstract

A newly developed Ar-BINMOL-Phos-controlled Rh/Cu-catalyzed (4+2) annulation of silacylcobutanes with arylpropiolate-type internal alkynes gave silicon-stereogenic 1-sila-2-cyclohexene derivatives with good ee and excellent chemoselectivity.
