Synthesis and Properties of Dichlorovinyl Derivatives of Tetrazoles

Abstract

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. © 2021, The Author(s).
