The carbonylative coupling of aniline derivatives (la-h) with terminal aryl
acetylenes (2a, b) catalyzed by Pd(OAc)(2) and 1,4-bis(diphenylphosphino)b
utane (dppb) under syngas conditions affords acrylamide derivatives 3 or 3'
in excellent yields and selectivities. (C) 2000 Published by Elsevier Scie
