O-Nucleophilic Amino Alcohol Acyl-Transfer Catalysts: the Effect of Acidity of the Hydroxyl Group on the Activity of the Catalyst
摘要:
[GRAPHIC]Amino alcohol-derived acyl-transfer catalysts are shown to operate by an O-nucleophilic mechanism, and catalysts bearing electron-withdrawing groups in proximity to the hydroxyl group are found to be more active. This is attributed to an increase in the acidity of the hydroxyl group of the catalyst.
