An unprecented N- and C(3)-dialkylation of unactivated amines by a cascade reaction via borrowing hydrogen methodology using new (arene)ruthenium(II) complexes featuring phosphinosulfonate ligands is described. This reaction is highly regioselective and produces water as the only side product.
描述了通过级联反应通过借位氢方法使用具有膦磺酸磺酸盐配体特征的新的(芳烃)钌(II)配合物进行级联反应的未活化胺的N-和C(3)-二烷基化。该反应是高度区域选择性的,并且产生水作为唯一的副产物。
