Sulfenylation of indole using sulfenyl chlorides leads to the initial formation of a 3-indolyl sulfide, while excess reagent introduces a second sulfide at the 2-position of the ring. The mechanism of this second sulfenylation has not, to date, been rigorously elucidated. The development of the first, regioselective synthesis of mixed indole 2,3-bis(sulfides) has allowed the study of the sulfenylation
使用亚磺酰氯进行吲哚的亚磺酰化会导致3-吲哚基硫化物的初步形成,而过量的试剂会在环的2-位引入第二个硫化物。迄今为止,尚未明确阐明第二次亚磺酰化的机理。混合吲哚2,3-双(硫化物)的第一个区域选择性合成的发展已经允许使用不同的亚磺酰氯进行3-吲哚基硫化物的亚磺酰基化的研究。我们的结果提供了证据,表明该反应是通过中间体3,3-二硫代化的吲哚烯进行的,随后其中一个硫化物基团迁移到了2位。
