Abstract:We describe a palladium catalyzed non-directed late-stage deuteration of arenes. Key aspects include the use of D2O as a convenient and easily available deuterium source and the discovery of highly active N,N-bidentate ligands containing an N-acyl sulfonamide group. The reported protocol enables high degrees of deuterium incorporation via a reversible C-H activation step and features an extraordinary functional group tolerance, allowing for the deuteration of complex substrates. This is exemplified by the late… Show more
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.
