example of a homogeneous catalyst based on an earth‐abundant metal for the hydrogenation of organic carbonates to methanol and alcohols is reported. Based on the mechanistic investigation, which indicates metal‐ligand cooperation between the manganese center and the N−H group of the pincer ligand, we propose that the hydrogenation of organic carbonates to methanol occurs via formate and aldehyde intermediates
报道了第一个基于稀土金属的均相催化剂的例子,该催化剂用于将有机碳酸盐氢化为甲醇和醇。基于机理研究,表明锰中心与钳型配体的N-H基团之间存在金属配体相互作用,我们建议通过甲酸酯和乙醛中间体将有机碳酸盐氢化为甲醇。该反应提供了将CO 2转化为甲醇的间接途径,再加上使用富含地球的催化剂,使整个过程对环境无害且可持续。
