A simple route to 9-fluorenylidenes by domino Suzuki/Heck coupling reactions
摘要:
A palladium catalyzed domino intermolecular Suzuki followed by intramolecular Heck coupling is described. This strategy afforded a novel and convenient synthesis of various 9-fluorenylidene derivatives in one-pot under relatively mild reaction condition. (C) 2011 Elsevier Ltd. All rights reserved.
