An efficient aluminum-catalyzed selective hydroboration of alkenes and alkynylsilanes is reported. A wide variety of alkenes and alkynylsilanes bearing various functional groups and heterocyclic substituents were converted to boronicester products in good yields with high selectivity. Mechanistically, density functional theory calculations favored a mechanism involving the insertion of the double
