摘要：
An efficient benzylic C-H amidation method was developed through copper-catalyzed C(sp3)-H/N-H cross dehydrogenative coupling between toluene derivatives and N-(8-quinolyl)amides. The 8-quinolyl group directed the activation of N-H bond without influence of quinoline C-H bonds or remote C(sp3)-H bonds. The reaction also showed broad substrate scope with good functional group compati-bility, producing various functionalized N-benzyl tertiary amides.(c) 2022 Elsevier Ltd. All rights reserved.
