The usage of earth-abundant, nontoxic transition metals in place of rare noble metals is a central goal in catalysis. This would be especially interesting when the reactivity and selectivity patterns can be tuned. Herein, we introduced the first Mn-catalyzed selective C-alkylation and olefination of fluorene, and indene with alcohols. Various substrates including benzylic, heteroaromatic, and aliphatic primary and secondary alcohols are employed as alkylating agents. Mechanistic investigations and a kinetic study underpin the involvement of the olefinated intermediate to furnish the alkylated product.

锰催化芴和茚与醇的可切换 C-烷基化/烯基化

使用地球上丰富的、无毒的过渡金属代替稀有贵金属是催化的中心目标。当可以调整反应性和选择性模式时，这将特别有趣。在此，我们首次介绍了 Mn 催化的芴和茚与醇的选择性C-烷基化和烯化。包括苄醇、杂芳族和脂肪族伯醇和仲醇在内的各种底物被用作烷化剂。机理研究和动力学研究支持烯化中间体的参与以提供烷基化产物。
