摘　　要：以苯肼和硫单质为原料,在无催化剂和空气气氛下,发展了一种二硫醚无臭、高效合成的新方法.该方法可以兼容—F,—Cl,—Br,—NO_(2),—CF_(3)及—MeO等多种官能团,可以拓展到萘环、吡啶环等其它类型芳基二硫醚的合成.与现有方法相比,该方法不需要使用过渡金属催化剂,无需化学计量的化学氧化剂和恶臭复杂的硫试剂,具有较好的实用价值.A catalyst-free,smell-less and efficient synthesis of disulfanes was developed from the reaction of phenylhydrazines and elemental sulfur under air atmosphere.This new method could tolerate various functional groups such as—F,—Cl,—Br,—NO_(2),—CF_(3) and—MeO groups,and could be easily extended to the synthesis of other aryl disulfanes such as 2-naphthyl disulfane and 2-pyridyl disulfane.Compared with the reported methods,this new method required no transition metal catalysts,no stoichiometric amount of oxidants,and no smelly and sophisticated sulfur reagents,showing good practical value.
