An ambient-light-promoted stereospecific olefinic C(sp2)–S bond construction of thioacids and 1,1-diarylethenes has been demonstrated, affording various (Z)-vinyl thioesters in 51–85% yields under solvent- and catalyst-free conditions. Mechanistic studies indicated that the formation of thioacid–olefin complexes is responsible for generating a carbonyl thiyl radical and dioxygen in the air participates
硫代酸和 1,1-二芳基乙烯的环境光促进的立体特异性烯属 C(sp 2 )–S 键结构已被证明,在无溶剂和无催化剂的情况下以 51–85% 的产率提供各种 ( Z )-乙烯基硫酯状况。机理研究表明,硫代酸-烯烃络合物的形成负责产生羰基硫基自由基,空气中的分子氧参与反应并充当无痕试剂。此外,代表性化合物3i的克级合成和聚集诱导发射特性已经证明了合成应用。
