摘要

2-Octynoic acid and phenylpropiolic acid were employed for the palladium-catalyzed decarboxylative coupling reaction and with a variety of aryl halides. The former needed 1, 4- bis (diphenylphosphino) butane (dppb) as a ligand and the latter tri-tert-butylphosphine (PtBu3), and both required 2 equiv of tetra-n-butylammonium fluoride (TBAF) for full conversion. These reactions showed high reactivities and tolerance of functional groups ...
