Intramolecular Heck Reactions of Unactivated Alkyl Halides
摘要:
A method has been developed for achieving palladium-catalyzed intramolecular Heck reactions of unactivated, beta-hydrogen-containing alkyl bromides and chlorides. The data from a stereochemical investigation are consistent with carbon-carbon bond formation via an alkylpalladium, rather than a radical, intermediate.
