chlorotrifluoromethylthiolation of alkenes by using a low-cost and more abundant iron catalyst has been developed. This protocol provides a straightforward way to synthesize a variety of useful SCF3-containing chlorides from a wide range of alkenes, including electron-deficient, aromatic, and unactivated alkenes. Mechanistic studies indicate that this is a free radical transformation, and the stronger electrophilic
通过使用低成本和更丰富的铁催化剂,开发了一种简单,方便的烯烃分子间氯三氟甲基硫醇化方法。该协议提供了一种直接的方法,可以从多种烯烃(包括缺电子的,芳族的和未活化的烯烃)合成各种有用的含SCF 3的氯化物。机理研究表明,这是一种自由基转化,在所采用的条件下,原位生成了更强的亲电子三氟甲基硫醇化试剂CF 3 SCl。还通过各种合成上有用的转换来探索这种方法的合成应用。
