The 4-, 5-, 6-, and 7-nitro derivatives of benzothiazole condense with ArN(MgBr)2 giving unsym-azoxy and -azo products. The product distribution indicated the mild nature of the reaction, and could be explained in terms of a reduced electron-donating ability of the reagent due to an interaction with thiazolyl group.
苯并噻唑的 4-、5-、6- 和 7-硝基衍生物与 ArN(MgBr)2 缩合生成非对称偶氮氧基和偶氮产物。产物分布表明反应性质温和,可以解释为由于与噻唑基相互作用导致试剂的给电子能力降低。
