A metal-free direct trifluoromethylthiolation of sulfonium ylides with an electrophilic trifluoromethylthiolating reagent has been established, in which sulfonium salt or α-bromoacetic ester is employed as sulfonium ylide precursors. This trifluoromethylthiolation enables the straightforward construction of SCF3-substituted sulfonium ylides from a wide range of substrates, including ketones, esters
已经建立了用亲电三氟甲基硫醇化试剂对锍叶立德进行无金属直接三氟甲基硫醇化,其中使用锍盐或α-溴乙酸酯作为锍叶立德前体。这种三氟甲基硫醇化能够直接从多种底物(包括酮、酯甚至 PEG 化底物)构建 SCF 3取代的锍叶立德。此外,还探索了该方法在大规模制备中的应用以及产品的荧光和氟19磁共振成像能力。
