Abstract
Gold-catalyzed oxidative cross-coupling of alkynes to unsymmetrical diynes has been achieved in the presence of 1,10-Phen as ligand and PhI(OAc)2 as oxidant giving the desired cross-coupled conjugated diynes in excellent heteroselectivity (>10:1), in good to excellent yields, and with large substrate tolerability.
