Under catalyst-free reaction conditions, solvent-mediated addition of thiol 2 to β-nitrostyrene 1 proceeded with regioselective control to afford either adduct 3 or vinyl sulfide 4 in good to excellent yield. Thermodynamic and autocatalytic reaction mechanisms were proposed to rationalize the products thus formed.
在无催化剂的反应条件下,溶剂介导的硫醇2加到β-硝基苯乙烯1中进行区域选择性控制,以良好或极好的收率得到加合物3或乙烯基硫化物4。为了使形成的产物合理化,提出了热力学和自催化反应机理。
