The present application discloses novel amino-sulfide metal catalysts for organic chemical syntheses including hydrogenation (reduction) of unsaturated compounds or dehydrogenation of substrates. The range of hydrogenation substrate compounds includes esters, lactones, oils and fats, resulting in alcohols, diols, and triols as reaction products. The catalysts of current application can be used to catalyze a hydrogenation reaction under solvent free conditions. The present catalysts also allow the hydrogenation to proceed without added base, and it can be used in place of the conventional reduction methods employing hydrides of the main-group elements. Furthermore, the catalysts of the present application can catalyze a dehydrogenation reaction under homogenous and/or acceptorless conditions. As such, the catalysts provided herein can be useful in substantially reducing cost and improving the environmental profile of manufacturing processes for a variety of chemicals.
本申请公开了一种新型氨基硫醚金属催化剂,用于有机化学合成,包括不饱和化合物的氢化(还原)或底物的脱氢。氢化底物化合物的范围包括酯类、内酯、油脂,生成醇、二醇和三醇作为反应产物。本申请的催化剂可用于在无溶剂条件下催化氢化反应。本申请的催化剂还允许氢化在无添加碱的情况下进行,并且可以代替使用主族元素的氢化物的传统还原方法。此外,本申请的催化剂可以在均相和/或无受体条件下催化脱氢反应。因此,本文提供的催化剂可用于大幅降低各种化学品制造过程的成本并改善其环境性能。
