Oxidation of N-alkyl-N'-tosylhy”razines with bromine yield alkyl bromides, vicinal alkyl dibromides and traces of alcohols. The main products of primary hydrazines are monobromides whereas secondary hydrazines preferably produce dibromides. The reaction proceeds with evolution of nitrogen and hydrobromic acid and by the formation of intermediate sulfinic ester which may be isolated. Various substrates
用溴氧化N-烷基-N'-甲苯磺酰肼,可生成烷基溴化物,邻烷基二溴化物和痕量的醇。伯肼的主要产物是一溴化物,而仲肼优选产生二溴化物。反应随着氮和氢溴酸的释放以及通过形成可以分离的中间体亚磺酸酯的进行而进行。在不同条件下检查了各种底物,以证实所假设的反应机理的有效性。
