A chiral diamine-based homogeneous cationic rhodium catalyst was developed and two heterogeneous cationic rhodium catalysts were obtained via the encapsulation of the homogeneous cationic rhodium catalyst within Me-SBA-15 and Me-SBA-16. All these catalysts presented excellent catalytic activities and high enantioselectivities in ultrasound-promoted asym. transfer hydrogenation of aromatic ketones and represent a successful use of the ion-pair immobilization strategy. More importantly, the encapsulation of the cationic rhodium functionality within Me-SBA-16 had an obvious high recyclability, in which the recycled catalyst could be reused nine times without significantly affecting its enantioselectivity, showing good potential in industrial application. In the experiment, the researchers used many compounds, for example, (R)-4-(1-Hydroxyethyl)benzonitrile (cas: 101219-69-6Related Products of 101219-69-6).
(R)-4-(1-Hydroxyethyl)benzonitrile (cas: 101219-69-6) belongs to nitriles. The electronic structure of nitriles is very similar to that of an alkyne with the main difference being the presence of a set of lone pair electrons on the nitrogen. In addition, Nitriles can react with alkynes, which leads to an increase in carbon chain length (carbocyanation).Related Products of 101219-69-6
