Amaya, Toru published the artcileSelective oxidative ligand coupling of organoborates bearing an alkynyl group, Formula: C23H20BN, the publication is Advanced Synthesis & Catalysis (2009), 351(7+8), 1025-1028, database is CAplus.
Selective 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.
Advanced Synthesis & Catalysis published new progress about 971-66-4. 971-66-4 belongs to pyridine-derivatives, auxiliary class Pyridine,Benzene, name is Triphenyl(pyridin-1-ium-1-yl)borate, and the molecular formula is C23H20BN, Formula: C23H20BN.
