The development of novel and efficient earth-abundant metal catalysts as inexpensive and sustainable alternatives to noble-metal catalysts is a rapidly expanding and evolving field of sustainable chemistry. In this context, manganese is a “rising star” that has made great progress for catalytic hydrogenation and dehydrogenation reactions since the seminal work reported in 2016. This review aims to provide a comprehensive picture of homogeneous Mn-catalyzed hydrogenation and dehydrogenation reactions from the beginning of 2016 till now. Various reactions are described, including the hydrogenation of unsaturated C–O, C–N, and C–C bonds; dehydrogenation of C1-molecules; and catalytic cascade dehydrogenative transformation of alcohols. Particular emphasis is placed on mechanistic understanding of manganese catalysts in these reactions. The future development trend of this promising field is also discussed.

作为贵金属催化剂的廉价且可持续的替代品，新型，高效的富含地球的金属催化剂的开发是可持续化学领域的一个快速扩展和发展的领域。在此背景下，锰是自2016年以来的开创性工作以来在催化加氢和脱氢反应方面取得了长足进步的“后起之秀”。该综述旨在从一开始就全面介绍均相锰催化的加氢和脱氢反应。 2016年至今。描述了各种反应，包括不饱和C–O，C–N和C–C键的加氢；C1-分子脱氢；和催化级联脱氢转化醇。特别强调在这些反应中对锰催化剂的机械理解。
