Selective sulfenylation of indoles with disulfides using iron(III) fluoride combined with iodine has been developed for the synthesis of sulfenylindoles. In the presence of iron(III) fluoride and iodine, a variety of disulfides underwent the reaction with indoles selectively to afford the corresponding sulfenylindoles in good to excellent yields. Moreover, reactions of indoles with 1,2-diphenyldiselane were also conducted under the same conditions, which smoothly afforded 3-selenylindoles in good yields.
利用氟化铁(III)和碘,开发了吲哚与二硫化物的选择性亚硫酰化反应,用于合成亚磺酰基吲哚。在氟化铁(III)和碘的存在下,多种二硫化物与吲哚发生选择性反应,生成相应的亚磺酰基吲哚,收率从良好到极佳。此外,在相同的条件下,吲哚与 1,2-二苯基二硒烷也发生了反应,并以良好的收率顺利得到了 3-硒基吲哚。
