The Ru(II)-catalyzed imidation of the o-C–H bond in arenes with N-tosyloxyphthalimide is realized with the assistance of a methyl phenylsulfoximine (MPS) directing group. This method is applicable to access the hitherto difficult o-C–H di-imidation products. The sequential C–N and C–C bond formation of o-C–H arenes creates peripherally decorated benzoic acid derivatives. The readily removable MPS-DG
N-甲苯磺酰氧基邻苯二甲酰亚胺在Ru(II)催化的芳烃中o -C-H键的酰亚胺化反应是通过甲基苯基亚磺酰亚胺(MPS)导向基团实现的。此方法适用于访问迄今困难的o -C–H二酰亚胺化产品。o -C–H芳烃的顺序C–N和C–C键形成会产生周边装饰的苯甲酸衍生物。易于除去的MPS-DG和易于修饰的邻苯二甲酰部分使该策略对于构建高度官能化的带有CN的芳烃和杂芳烃具有可行性。
