Usage | 4-Dimethylaminopyridine is a highly efficent catalyst widely used in organic synthesis.The resonance between the electron-donating group dimethylamino and the pyridine ring can strongly activate the nitrogen atom for nucleophilic substitution, therefor remarkably catalyse the acylation ( phosphorylation, sulphonyation, carbonylation ) of alcohols or amines which have high steric hindrance and low reacitivity. The catalytic activity and can increase largely the yield in a number of reactions, such as acylation, alkylation, etherification, and transesterfication. |
