Rh(III)‐catalyzed acetylation of sp2 C−H bonds has been realized using paraformaldehyde as an acetylating reagent. This procedure features simultaneous formation of two C−C bonds, external oxidants free, and water as the sole byproducts, thus offering an environmentally benign acetylation of arenes. A range of functional groups tolerance were observed.
Rh(III)催化的sp 2 CH键的乙酰化已使用低聚甲醛作为乙酰化试剂实现。该程序的特征是同时形成两个C-C键,无外部氧化剂,并且水是唯一的副产物,因此提供了芳烃对环境无害的乙酰化作用。观察到一定范围的官能团耐受性。
