The highly linear-selective hydroaminomethylation of styrenes is very challenging. Herein, an efficient, highly chemoselective, and linear-selective hydroaminomethylation (l/b up to >99:1) of styrenes using Rh(nbd)2SbF6 with a pyrrole-based 3,3′,5,5′-substituted tetraphosphorus ligand is documented. This is in sharp contrast to other available processes leading to branched amines and provides a novel
苯乙烯的高度线性选择性的氢氨基甲基化是非常具有挑战性的。本文中,使用具有吡咯基3,3',5,5'-取代的Rh(nbd)2 SbF 6的苯乙烯高效,高度化学选择性和线性选择性氢氨基甲基化(l / b高达> 99:1)记录了四磷配体。这与导致支链胺的其他可用方法形成鲜明对比,并为3-芳基丙胺提供了一种新颖的原子经济方法。
