Abstract
1-Substituted 1H-tetrazole-5-thiols and 5-substituted 1H-tetrazoles easily reacted with trichloroethylene to form the corresponding S- and N-dichlorovinyl derivatives, respectively. In the case of 5-substituted 1H-tetrazoles, the reaction led to a mixture of 1- and 2-dichlorovinyltetrazoles. 5-Substituted-2-dichlorovinyltetrazoles are characterized by low thermal stability, but easily enter into the polymerization reaction.
摘要
1-取代的 1H-四唑-5-硫醇和 5-取代的 1H-四唑很容易与三氯乙烯反应,分别生成相应的 S-和 N-二氯乙烯基衍生物。对于 5-取代的 1H-四唑,反应生成 1-和 2-二氯乙烯基四唑的混合物。5-取代-2-二氯乙烯基四唑的特点是热稳定性低,但很容易进入聚合反应。
