N-Arylimines and 1-methyl-1-phenylhydrazones of diaryl ketones were prepared, their yields being affected by the electronic and positional effects of substituents of reagent and substrate. Direct preparation of some anils of xanthone and its 1-methyl-1-phenylhydrazone was achieved by use of the corresponding iminodimagnesium reagents.
研究了酮与衍生自各种伯胺和 1,1-二取代肼的亚氨基二镁试剂 (RN(MgBr)2) 的缩合反应。制备了二芳基酮的N-芳基亚胺和1-甲基-1-苯基腙,其产率受试剂和底物取代基的电子和位置效应的影响。通过使用相应的亚氨基二镁试剂,实现了一些呫吨酮及其1-甲基-1-苯腙的直接制备。
