A strategy to introduce the SCF3 group through the CuI-promoted reaction of diazocompounds with the nucleophilic AgSCF3 trifluoromethylthiolation reagent was developed. Various diazocompounds were smoothly converted under mild conditions to form the C(sp3)–SCF3 bond. Mechanistically, migratoryinsertion of SCF3-bearing Cu carbene intermediates is involved in this transformation.
开发了一种通过 CuI 促进的重氮化合物与亲核 AgSCF3 三氟甲基硫醇化试剂反应引入 SCF3 基团的策略。各种重氮化合物在温和条件下顺利转化为 C(sp3)-SCF3 键。从机制上讲,这种转变涉及含 SCF3 的 Cu 卡宾中间体的迁移插入。

A boron-catalyzed direct α-trifluoromethylthiolation of carboxylicacids was developed. Catalytically generated boron enediolates reacts with electrophilic SCF3 reagent, N-SCF3-phthalimide, to provide α-SCF3 carboxylicacids without the need of substrate pre-activation. The method is applicable to direct modification of bioactive carboxylicacids. Data science analyses provided suitable models for
A practical protocol for hydrotrifluoromethylthiolation of diazo compounds has been developed. A range of diazo compounds in combination with a nucleophilic SCF3 source provided access to valuable trifluoromethylthiolated compounds. Furthermore, a methodology for the first double trifluoromethylthiolation was developed.
