Merck, 39405-250G, 4-(Dimethylamino)pyridine

General description
4-(Dimethylamino)pyridine is generally employed as a catalyst in the acylation of amines, alcohols, enolates, and phenols. It can also be used in the esterification of carboxylic acids. It is known to exhibit good catalytic activity in non-polar solvents.
Application
4-(Dimethylamino)pyridine can be used:
As a capping agent in the preparation of water-soluble gold nanoparticles.
As an initiator in the polymerization of epoxy monomers.
As an auxiliary reagent in the electroless preparation of gold nanotubes applicable in catalysis.
As a catalyst in the preparation of γ- and δ-lactones via iodolactonization of γ,δ-unsaturated carboxylic acids.

A highly efficient catalyst for acylation reactions
Other Notes
Hypernucleophilic acylation catalyst.
