2-Dimethylaminopyridine Usage And Synthesis

Chemical Properties

Clear colorless to pale yellow liquid

Uses

2-(Dimethylamino)pyridine in toluene at room temperature in the presence of 1.1 equivalent of methyl trifluoromethanesulfonate forms (2-pyridyl)-trimethylammonium trifluoromethanesulfonate salt. It is used as a model substrate in the preparation of chelate carbene via cyclometalation, H2 loss and reversible α-elimination.

General Description

2-(Dimethylamino)pyridine is a clear, colorless to light yellow liquid.

Safety Profile

A poison by intravenous route. When heated to decomposition it emits toxic vapors of NOx
