One Pot Synthesis of<i>p</i>-Polyphenyls<i>via</i>the lntramolecular Cyclization of 3-Dimethyl-aminohex-5-en-1-ynes

Abstract

Para linked polyphenyls of various molecular weights are conveniently synthesized from p-bis(3-dimethylamino-1-propynyl)arenes and 1-aryl-2-propenyl bromides in moderate yields using a three step, one-pot procedure.
