An efficient method for the visible-light-induced radical trifluoromethylation/cyclization of N-arylacrylamides with trifluoromethyl phenyl sulfone was developed.
Sulfide is a widely occurring natural product and pharmaceutically active compound. This review highlights the photochemically mediated thioether synthesis reactions, with emphasis on catalytic mechanism.
Coupling of sulfones and alcohols catalyzed by Ni(OAc)2/P(t-Bu)3 undergoes α-alkylation while β-olefination proceeds in the presence of a base and air.
Herein, by applying visible-light photoredox catalysis, we achieved the first example of catalytic dehydrogenative coupling of thiophenols and alkynes for the synthesis of thioacetylenes at room temperature under mild reaction conditions.
An electrochemically promoted oxidative dehydrogenation cross-coupling reaction between aldehyde hydrazones and thiophenols is demonstrated for the first time, which results in a variety of thioetherified products in moderate to excellent yields.
