The benzoin condensation of aromatic and heteroaromatic aldehydes, catalyzed by electrochemically generated N-heterocyclic carbenes, has been set up in the absence of organic solvents and bases. a-Hydroxy ketones have been isolated in good to elevated yields, in short reaction times. Aldol products and carbene-aldehyde adducts have been obtained in elevated yields from linear and short branched aldehydes, respectively. A comparison with the use of classical organic solvents has been reporte
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
