When several azole derivatives such as imidazole, thiazole, and oxazole are treated with a catalyst system of copper(II)/silver(I) under oxygen atmosphere, oxidative dimerization at the CH bond of the 2-position takes place to afford the corresponding bisazoles up to 86% yield.
在氧气氛下,使用铜(II)/银(I)的催化剂体系处理几种咪唑衍生物(如咪唑,噻唑和恶唑)时,会在2-位的CH键处发生氧化二聚,得到相应的双唑产率高达86%。
