A highly efficient and convenient CuCl/2-pyridonate catalytic system for oxidative homocoupling of azoles affording a biazole product has been developed. With this system, a variety of biazoles have been effectively synthesized in good to excellent yields in the presence of a very small amount of copper catalyst (1.0 mol%). It was feasible to employ air as a green oxidant.
已经开发了一种高效且方便的CuCl / 2-吡啶酮催化体系,用于氧化制提供双唑产物的吡咯。利用该系统,在非常少量的铜催化剂(1.0摩尔%)的存在下,已经以良好至优异的收率有效地合成了多种联唑。使用空气作为绿色氧化剂是可行的。
