benzoxazine bearing thiol moiety 1 was synthesized from its precursor, a bifunctional benzoxazine bearing disulfide linkage, through selective reduction of the disulfide. The thiol moiety thus formed readily reacted with glycidyl phenyl ether to give the corresponding benzoxazine 3a, which exhibited much higher polymerization ability than some referential monomers without sulfide moiety.
通过选择性地还原二硫化物,由其前体,即具有二硫键的双官能苯并恶嗪,合成了具有硫醇基部分1的苯并恶嗪。如此形成的硫醇部分容易与缩水甘油基苯基醚反应,得到相应的苯并恶嗪3a,与没有硫化物部分的某些参考单体相比,苯并恶嗪3a具有更高的聚合能力。
