general approach for the one-pot hydroaminomethylation of olefins using methylformate as formylating agent instead of synthesis gas (syngas) has been proposed. Herein we report that a Ru–Rh catalytic system demonstrates high activity in a tandem conversion of a series of n-alkenes into amines using methylformate with yields 58–92% (6 h). The selectivity for the normal amine reached 96% with catalysis by
已经提出了一种新的通用方法,该方法使用甲酸酯甲酯作为甲酰化剂代替合成气(合成气)进行一锅法烯烃的氢氨基甲基化。本文中,我们报道Ru-Rh催化体系在使用甲酸甲酯的一系列正构烯烃串联转化为胺中表现出高活性,产率为58-92%(6小时)。在Ru羰基络合物Ru 3(CO)12的催化下,对正胺的选择性达到96%,在这种情况下,相对于胺,总产率为55%。在Ru催化体系中添加Rh络合物,可显着提高末端和内部烯烃的氢氨甲基化率,并将胺的收率提高至82-93%(6-12小时)。
