manganese-catalyzed N-alkylation reaction of amines with alcohols via hydrogen autotransfer strategy has been demonstrated. The developed practical catalytic system including an inexpensive, nontoxic, commercially available MnCl2 or MnBr(CO)5 as the metal salt and triphenylphosphine as a ligand provides access to diverse aromatic, heteroaromatic, and aliphatic secondary amines in moderate-to-high yields
已经证明了通过氢自动转移策略的锰与醇的锰催化的N-烷基化反应。已开发的实用催化系统包括廉价,无毒,可商购的MnCl 2或MnBr(CO)5作为金属盐,以及三苯基膦作为配体,可提供中等至高收率的多种芳族,杂芳族和脂族仲胺。另外,该操作简单的方案可扩展至克水平,并且适合于合成已知对阿尔茨海默氏病具有活性的杂环,例如吲哚和白藜芦醇衍生的胺。
