universal and efficient Cu(I)-catalyzed synthesis of aryl and alkyl trifluoromethyl sulfides has been developed. In this catalytic system, S-aryl or S-alkyl sulfothioate (I or II) proved to be the key intermediate. Substrates bearing groups of I, Br, Cl, OTs, and OMs on the aryl carbon and no matter electron-withdrawing and electron-donating substitutions on the aromatic ring could afford good to excellent
已经开发出通用且有效的Cu(I)催化的芳基和烷基三氟甲基硫醚的合成方法。在该催化体系中,S-芳基或S-烷基磺基硫酸酯(Ⅰ或Ⅱ)被证明是关键的中间体。在芳基碳上带有I,Br,Cl,OTs和OMs的基团的基团,无论芳环上有吸电子和供电子取代基,都可以提供优异的良率。
