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
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。
