Platinum- and Palladium-Catalyzed Sequential Reactions: Regioselective Synthesis of 9-Fluorenylidenes from 9-Ethynylfluoren-9-yl Carboxylates and Furans
The transformation of 9-acyloxy-9-ethynylfluorene and furans with platinum and palladium co-catalysts gave 9-fluorenylidenes in excellent yields with high regioselectivity in a one-pot manner.
