The present invention provides a method for the preparation of a wide range of primary arylamines. The arylamines are prepared in two efficient, straightforward transformations: 1) an activated aryl group and an imine group are combined, in the presence of a transition metal catalyst, under conditions wherein the transition metal catalyst catalyzes the formation of a carbon-nitrogen bond between the activated carbon of the arene and the imine nitrogen; and 2) the resulting N-aryl imine is transformed, via any of a number of standard protocols, to the primary arylamine. The method of the invention may also be exploited in the preparation of vinylamines.
本发明提供了一种制备广泛范围的主要芳胺的方法。这些芳胺是通过两种高效、直接的转化制备的:1)在过渡金属催化剂的存在下,将活化的芳基和亚胺基结合在一起,在过渡金属催化剂催化的条件下,在芳烃的活化碳和亚胺氮之间催化形成碳-氮键;2)通过任何一种标准方案将产生的N-芳基亚胺转化为主要芳胺。该发明的方法还可用于制备乙烯胺。
