摘要

The "Y" donor group (Y = -OMe, -SEt, -PPh2, -NH2, -NMe2, -Py, pyrrolidinyl, quinolyl) of the pincer-type ruthenium complexes RuHCl(CO)[kappa(3)-YNP] has a dramatic influence on the catalytic activity in the dehydrogenative homocoupling and cross-coupling of ethanol and ester hydrogenation reactions. The observations are connected with the mechanisms of the catalytic reactions, and this paper provides evidence for ester C-O bond formation/cleavage assisted by the bifunctional catalysts in an outer-sphere fashion, reminiscent of the Tishchenko chemistry.
