We developed hydroxysulfurization and alkoxysulfurization of styrenes using a visible‐light synthetic strategy in the absence of photocatalyst and oxidant. This strategy provided the corresponding β‐hydroxysulfides and β‐alkoxysulfides in moderate to good yields with high regioselectivity. The reaction was tolerated by a wide range of functional groups. This is the first example of ArSSAr/CBr4 system has been introduced into organic transformation.
The chemoselectivity of visible-light-induced coupling reactions of bromoalkynes with alcohols can be controlled by simple changes to the reaction atmosphere.
A straightforward synthesis of alkynylthioethers via an amino-assisted and visible-light-promoted coupling reaction of bromoalkynes with 2,2′-diaminodiphenyldisulfides is developed. The reaction can be accomplished in the absence of transition-metal, photocatalyst and...
The controllable achievement of CC and C-P bond formations is developed via visible-light-promoted bromoalkyne dimerization or its further transformation with secondary phosphine oxides. The 1,1-dibromo-1-en-3-ynes are formed when bromoalkyne is exposed to visible-light. While alkynylphosphine oxides are generated when bromoalkynes are mixed with secondary phosphine oxides.
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.
