The catalytic nitrile hydration using ruthenium catalysts based on a pincer scaffold with a dearomatized pyridine backbone. These complexes catalyzed the nucleophilic addition of H2O to a wide variety of aliphatic and (hetero)aromatic nitriles in tBuOH as solvent. Reactions occurred under mild conditions (room temperature) in the absence of additives. A mechanism for nitrile hydration was proposed that is initiated by metal-ligand cooperative binding of the nitrile. The experimental process involved the reaction of 4-Cyanopyridine(cas: 100-48-1Quality Control of 4-Cyanopyridine)
4-Cyanopyridine(cas: 100-48-1) belongs to pyridine. When pyridine is adsorbed on oxide surfaces or in porous materials, the following species are commonly observed: (i) pyridine coordinated to Lewis acid sites, (ii) pyridine H-bonded to weakly acidic hydroxyls, and (iii) protonated pyridine. At high coverage, physisorbed pyridine and protonated dimers can also be observed.Quality Control of 4-Cyanopyridine
