  摘要：

  A photocatalyzed formal (3+2) cycloaddition has been developed to construct original polysubstituted α‐SCF3 cyclopentanones in a regio‐ and diastereoselective manner. This building block approach leverages trifluoromethylthio alkynes and branched / linear aldehydes, as readily available reaction partners, in consecutive hydrogen atom transfers and C–C bond formations. Difluoromethylthio alkynes are also compatible subtrates. Furthermore, the potential for telescoped reaction starting from alcohols instead of aldehydes was demonstrated, as well as process automatization and scale‐up under continuous microflow conditions. This prompted density functional theory calculations to support a free radical‐mediated cascade hydrogen atom transfer process.

  The direct trifluoromethylthiolation of terminal alkynes is an important strategy for accessing CF3S-containing compounds. Herein, we report a direct trifluoromethylthiolation reaction of various terminal alkynes employing a new hypervalent trifluoromethylthio-iodine(III) reagent TFTI in a fluorinated alcohol, either 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP) or perfluoro-tert-butanol (PFTB). The reaction

  末端炔烃的直接三氟甲硫基化是获得含CF 3 S化合物的重要策略。在此，我们报道了使用新型高价三氟甲硫基碘 ( III ) 试剂 TFTI 在氟化醇（1,1,1,3,3,3-六氟-2-丙醇 (HFIP)）中对各种末端炔烃进行直接三氟甲硫基化反应或全氟叔丁醇（PFTB）。基于实验和DFT计算提出了反应机理。 TFTI 的可持续性和 PFTB 的回收使得反应环境友好。而且，根据绿色化学指标评估和 EcoScale 评分，该协议被认为是绿色化学背景下的优秀协议。

  A metal-free oxidative trifluoromethyl-thiolation of terminal alkynes using readily available CF(3)SiMe(3) and elemental sulfur at room temperature has been developed. This reaction provides an efficient and convenient method for the preparation of alkynyl trifluoromethyl sulfides bearing a wide range of functional groups. Preliminary investigation revealed that elemental sulfur instead of air acted
