摘要

Abstract Pd-catalyzed domino synthesis of 1, 3-diynes was accomplished using 1, 1- dibomoalkenes under copper-free coupling conditions. This domino procedure involves base mediated in situ generation of 1-bromoalkyne and its subsequent coupling to give 1, 3- diyne. The optimized copper-free coupling method afforded good to high yields of symmetrical 1, 3-diynes in a one-pot operation.
