investigated the reactivity of acrylamides with sulfur and eventually developed a new pseudo-multicomponent reaction for the preparation of polysulfides. Sequential one-pot reduction led to diversely substituted thiols. Additional third stage one-pot modifications provided thioethers, unsymmetric disulfide and thioester.
元素硫能够方便地形成 C-S 键和直接掺入 S-S 键。然而,几乎没有公开容易获得的缺电子烯烃对硫的反应性。在此,我们研究了丙烯酰胺与硫的反应性,并最终开发了一种新的准多组分反应来制备多硫化物。连续的一锅还原导致多种取代的硫醇。额外的第三阶段一锅法修饰提供了硫醚、不对称二硫化物和硫酯。
