摘要

Synthesis of five and six membered heterocycles, indolines, 2, 3-dihydrobenzofurans, chromans, isochromans, 1, 2, 3, 4-tetrahydroquinolines, and 1, 2, 3, 4- tetrahydroisoquinolines, in 70–99% yield by a ligand-free palladium catalyzed reductive Heck cyclization of phenyl bromides and chlorides, under mild conditions, is reported. Water was found to be essential for these reactions.
