4-Dimethylaminopyridine (DMAP) is a derivative of pyridine with the chemical formula (CH3)2NC5H4N. This white 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 … See more DMAP can be prepared in a two-step procedure from pyridine, which is first oxidized to 4-pyridylpyridinium cation. This cation then reacts with dimethylamine: See more DMAP has a relatively high toxicity and is particularly dangerous because of its ability to be absorbed through the skin. It is also corrosive.
