Lewis Acid Enhancement of Gold Catalytic Activity Through Counterion Coordination. Synthesis of Benzofulvenes from Progargylsilanes and Benzophenones
intermediates, such as enynes and silylbenzofulvenes, have been isolated. Different control experiments have been performed, indicating the participation of [LAu][NTf2AlCl3] complex as the true catalyst, and revealing a dramatic enhancement of the gold activity by coordination of the Lewis acid to the gold counterion.
