DMAP(4-dimethylaminopyridine)[a high efficient catalyst used in pesticide]

Is a acylation catalyst used in the synthesis of agrochemicals, pharmaceuticals and polymers
can used in clethodim and Pyriprox

4-Dimethylaminopyridine is a acylation catalyst used in the synthesis of agrochemicals, pharmaceuticals and polymers. It is used as a coupling agent for the synthesis of peptide.

 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.
