A synthetic method was developed for the preparation of vinyl sulfides and vinylamines from arylalkynyl phenyl sulfides and sulfonamides. Under mild conditions, a catalytic intramolecular hydroarylation reaction was carried out in the presence of FeCl3 and AgOTf (OTf = trifluoromethanesulfonate) in 1,2-dichloroethane. A variety of 1,2-dihydronaphthalenes, 2H-chromenes, and 1,2-dihydroquinolines containing
开发了一种由芳基炔基苯基硫化物和磺酰胺制备乙烯基硫化物和乙烯基胺的合成方法。在温和条件下,在 FeCl3 和 AgOTf(OTf = 三氟甲磺酸盐)的存在下,在 1,2-二氯乙烷中进行催化分子内加氢芳基化反应。各种 1,2-二氢萘、2H-色烯和 1,2-二氢喹啉在 sp2 杂化的苄基碳上含有苯硫基或 N-苯基-N-甲苯磺酰基,以良好到极好的产率制备。本方法可以扩展到通过选择性 6-endo 模式通过双重 Fe 催化加氢芳基化制备二氢吡喃并 [2,3-g] 色烯。
