Designing a new basic ionic liquid [DHIM][OH] as a task specific bifunctional catalyst for facile microwave assisted metal free synthesis of 5-amino-1,2,3-triazoles

Abstract

A green protocol for the synthesis of a series of 5-amino-1,2,3-triazoles from benzyl cyanide and phenyl azide derivatives catalyzed by the novel bifunctional ionic liquid [DHIM][OH] under microwave irradiation has been developed. The bifunctional ionic liquid which acts as a catalyst can be accessed through rapid preparation via incorporation of microwave irradiation. To the best of our knowledge, the present approach is the first method to employ an organocatalyst under microwave irradiation to access rapid assembly of 5-amino-1,2,3-triazoles under mild conditions. Furthermore, small E-factor values associated with the products confirm greener attributes of the current protocol.
