Abstract

Abstractmagnified imageSelective oxidative ligand coupling of alkynyl(triaryl)borates was achieved by treatment with ethoxyvanadyl dichloride [VO(OEt)Cl2] to form the spsp2 carbon‐carbon bond. A one‐pot procedure through the in situ preparation of the borate was demonstrated using triphenylborane and 1‐ethynyl‐4‐methoxybenzene.
