A detailed study of literature-known and novel S-containing pincer-type ligands for ruthenium-catalyzed homogeneous hydrogenation and dehydrogenation reactions was carried out. The scope and limitations of these catalysts were carefully investigated, and it was shown that simple bench-stable SNS–Ru complexes can be used to facilitate the hydrogenation of a variety of different substrates at a maximum H₂ pressure of 20 bar under operationally simple, easy to scale up, glovebox-free conditions by using starting materials and reagents that do not require any special purification prior to use. It was also shown that such complexes can be used to catalyze the dehydrogenative coupling of alcohols and amines to get amides as well as for the dehydrogenative dimerization of alcohols to esters.

SNS配体用于Ru催化的均相加氢和脱氢反应

对已知的和新颖的含S的钳型配体进行了钌催化的均相加氢和脱氢反应的详细研究。仔细研究了这些催化剂的范围和局限性，结果表明，简单的工作台稳定的SNS-Ru络合物可用于在操作简单，最大H ₂压力为20 bar的条件下促进各种不同底物的氢化，通过使用不需要在使用前进行任何特殊纯化的起始原料和试剂，即可轻松实现规模化，无手套操作的条件。还显示出这种络合物可用于催化醇和胺的脱氢偶联以得到酰胺，以及用于醇脱氢二聚为酯。
