The atom transfer radical addition (ATRA) reaction is defined as a method for introducing halogenated compounds into alkenes via mechanism. In this study, we present an ATRA approach achieving regioselective functionalization of quinoxalin-2(1H)-ones by activating C–Br bonds CBr4 and subsequent trihaloalkyl-carbofunctionalization styrenes employing the 9-mesityl-10-methylacridinium perchlorate (Fukuzumi) photocatalyst under 3W blue LED (450–470 nm) irradiation. This three-component cascade process demonstrates remarkable efficiency in synthesis 1-methyl-3-(3,3,3-tribromo-1-(4-chlorophenyl)propyl)quinoxalin-2(1H)-one derivatives.

Without any additives and photocatalysts, the visible-light-promoted radical cascade reaction between alkynoates phenyl disulfides has been developed at room temperature. Through S–S bond photolysis homolytic cleavage, addition of a sulfur radical, aryl migration, decarboxylation, H atom abstraction, provides an efficient practical route to trisubstituted 1,1-diarylvinylsulfides with wide scope substrates good excellent yields.
