We have developed unprecedented methods for the direct transformation of primary alcohols to alkenes in the presence of hydrazine, and for the synthesis of mixed alkenes by the reaction of alcohols with hydrazones. The reactions are catalyzed by a manganese pincer complex and proceed in absence of added base or hydrogen acceptors, liberating dihydrogen, dinitrogen, and water as the only byproducts
我们已经开发出前所未有的方法,用于在
肼存在下将伯醇直接转化为烯烃,以及通过醇与的反应合成混合烯烃的方法。该反应由
锰钳配合物催化,并且在不添加碱或氢受体的情况下进行,释放出二氢,二氮和
水作为唯一的副产物。基于所提出的中间体的制备和对照实验,所提出的机理表明该转化是通过through中间体的
金属-
配体协同NH活化而发生的。
