General description

2-Dimethylaminoethanol (deanol, DMAE) is a precursor of acetylcholine. Microwave spectral studies on DMAE have reported the following values; the rotational constants (MHz) A = 5814.0(2), B = 2214.54(2), and C = 2037.96(2) and a dipole moment of 2.56 D, with a, b, and c components (D) of 2.27(2), 0.3(1), and 1.16(5), respectively.

Application

2-Dimethylaminoethanol (deanol, DMAE) may be employed as a ligand in the copper-catalyzed amination of aryl bromides and iodides.
