4 – Dimethyl Amino Pyridine
₹1,800.00
4-(Dimethylamino)pyridine (DMAP) is a toxic, corrosive solid that is widely used as a nucleophilic catalyst in esterification, hydrosilylation, Bayliss–Hillman reactions, and many more. In 2001, G. C. Fu and co-workers showed that chiral derivatives of DMAP can be used for stereoselective catalysis.

discription-4-Dimethylaminopyridine (DMAP) is a derivative of pyridine with the chemical formula (CH3)2NC5H4N. This colourless solid is of interest because it is more basic than pyridine, owing to the resonance stabilisation from the NMe2 substituent.
Because of its basicity, DMAP is a useful nucleophilic catalyst for a variety of reactions such as esterifications with anhydrides, the Baylis-Hillman reaction, hydrosilylations, tritylation, the Steglich rearrangement, Staudinger synthesis of β-lactams and many more. Chiral DMAP analogues are used in kinetic resolution experiments of mainly secondary alcohols and Evans auxiliary type amides.
DMAP has a relatively high toxicity and is particularly dangerous because of its ability to be absorbed through the skin. It is also corrosive.
