Aminocarbene mechanism of the formation of a tertiary amine in nitrile hydrogenation on a palladium catalyst

Popis výsledku v původním jazyce

The hydrogenation of an aliphatic nitrile, molecules of which do not bear hydrogen atoms on the alpha-carbon with respect to the nitrile group, has been studied to gain a deeper insight into the mechanism of the heterogeneously catalyzed hydrogenation ofnitriles. Hydrogenations were performed in the liquid phase on a Pd/C catalyst at a reaction temperature of 110 A degrees C and a hydrogen pressure of 5 MPa. In the hydrogenation of trimethylacetonitrile in the presence of a lower aliphatic N,N-dialkylamine (e.g., diethylamine), the formation of a mixed tertiary amine, dialkylneopentylamine, was observed. Experiments have shown that the disproportionation reactions of the amines present are not responsible for its formation. Since the corresponding enamine incorporating a double bond in the neopentyl chain cannot be derived from the dialkylneopentylamine, the formation of the dialkylneopentylamine cannot be explained in terms of the enamine theory of the formation of a tertiary amine d
