Abstract
Metal-ligand cooperation (MLC) plays an important role in catalysis. Systems reported so far are generally based on a single mode of MLC. We report here a system with potential for MLC by both amine-amide and aromatization- dearomatization ligand transformations, based on a new class of phosphino-pyridyl ruthenium pincer complexes, bearing sec-amine coordination. These pincer complexes are effective catalysts under unprecedented mild conditions for acceptorless dehydrogenative coupling of alcohols to esters at 35 degrees C and hydrogenation of esters at room temperature and 5 atm H-2. The likely actual catalyst, a novel, crystallographically characterized monoanionic de-aromatized enamido-Ru-II complex, was obtained by deprotonation of both the N-H and the methylene proton of the N-arm of the pincer ligand.
