title: Palladium-catalyzed synthesis of benzosilolo[2,3-b]indoles via cleavage of a C(sp3)-Si bond and consequent intramolecular C(sp2)-Si coupling.
abstract: An efficient process involving Pd-catalyzed selective cleavage of a C(sp(3))-Si bond and consequent intramolecular C(sp(2))-Si coupling has been developed, affording benzosilolo[2,3-b]indoles as a new type of silicon-bridged polyheteroarene in excellent yields. Aldehyde was found for the first time to be able to promote the efficiency of the catalytic process remarkably.
