Abstract
Abstract The intermolecular oxidative coupling of arylboronic acids with internal alkynes efficiently proceeds in a 2: 2 manner in the presence of palladium acetate, a triaryl phosphite or phosphate, and silver carbonate as catalyst, ligand, and oxidant, respectively, to produce the corresponding 1, 4-diaryl-1, 3-butadiene derivatives.
