The alkylation of the ortho C-H bonds in benzamides and acrylamides containing an 8-aminoquinoline moiety as a bidentate directing group with unactivated alkyl halides using nickel complexes as catalysts is described. The reaction shows high functional group compatibility. In reactions of meta-substituted aromatic amides, the reaction proceeds in a highly selective manner at the less hindered C-H bond
描述了使用镍配合物作为催化剂,使用未活化的卤代烷对苯甲酰胺和含有 8-氨基喹啉部分作为双齿导向基团的苯甲酰胺和丙烯酰胺中的邻位 CH 键进行烷基化。该反应显示出高度的官能团相容性。在间位取代芳香酰胺的反应中,反应在受阻较小的 CH 键上以高度选择性的方式进行。
