The
carbon–sulfur (C–S) bond formation reactions
enabled by N-heterocyclic carbene (NHC) organocatalysis
are systematically summarized in this review. Diverse transformations
involving NHC-catalyzed S-esterification, NHC-catalyzed nucleophilic
S-conjugate addition, NHC-catalyzed S-addition reactions with electrophiles,
and C–S bond formations via cooperative NHC/transition metal-catalyzed
radical reactions are introduced and discussed. Our own comprehension
and perspectives on this highly active research field are also provided
at the end of this review.
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.
