The hydroalkylation and hydroacylation of electrondeficient alkenes proceeded smoothly by using benzothiazoline derivatives as radical-transfer reagents under thermal conditions without light irradiation or any additive. Both benzyl and benzoyl moieties were transferred efficiently.
A visible-light mediated, catalyst-free hydroalkylation of electron-deficient alkenes was achieved using benzothiazoline as a radical transfer reagent. The photoreaction proceeded under household LEDs. Mechanistic studies elucidated the formation of an electron-donor-acceptor complex between benzothiazoline and electron-deficient alkenes.
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.
