 4-Dimethylaminopyridine is a highly efficient catalyst widely used in organic sythesis.

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.
