A Ni-catalyzed
cross-coupling of readily accessible O-alkyl xanthate
esters or thiocarbonyl imidazolides and organozinc
reagents for the synthesis of thiocarboxylic acid derivatives has
been developed. This method benefits from a fast reaction time, mild
reaction conditions, and ease of starting material synthesis. The
use of transition-metal catalysis to access a diverse range of thiocarbonyl-containing
compounds provides a useful complementary approach when compared with
previously established methodologies.
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.
