Abstract
N-heterocyclic carbenes, electrogenerated by cathodic reduction of imidazolium-based room temperature ionic liquids (RTILs), are stable bases able to catalyze the Henry reaction. Accordingly, the electrosynthesis of beta-nitroalcohols has been achieved, under mild conditions and in high yields, by stirring nitromethane and aldehydes in previously electrolyzed RTILs. RTILs have been used as green solvents as well as precursors of N-heterocyclic carbenes. (c) 2009 Elsevier B.V.
