The first manganese(I)‐catalyzed C−H allylations with ample scope were achieved by carboxylate assistance. The highly selective C−H/C−O functionalizations proved viable with densely substituted allyl carbonates, and the organometallic C−H allylation strategy set the stage for expedient late‐stage diversification with excellent levels of positional selectivity.
通过羧酸盐的辅助作用,第一个锰(I)催化的CH烯丙基化作用范围很大。事实证明,高选择性的C / H / C-O功能化可用于稠密取代的碳酸烯丙酯,有机金属的C-H烯丙基化策略可为后期分散化提供有利的条件,并具有出色的位置选择性。

Aromatic C–H allylation of N-sulfonyl ketimines with allyl alcohol or allyl phenyl ether as an allyl source is catalyzed by a cationic iridium complex. The presence of a catalytic amount of a pyridine derivative was found to be essential for the reaction. In contrast, direct C–H allylation of ketimines derived from benzophenone derivatives and p-methoxyaniline with allyl phenyl ether proceeded in the
