Selective oxidative ligand coupling of alkynyl(triaryl)borates was achieved by treatment with ethoxyvanadyl dichloride [VO(OEt)Cl(2)] to form the sp-sp(2) carbon-carbon bond. A one-pot procedure through the in situ preparation of the borate was demonstrated using triphenylborane and 1-ethynyl-4-methoxybenzene.
