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
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] undermicrowaveirradiation has been developed. The bifunctional ionic liquid which acts as a catalyst can be accessed through rapid preparation via incorporation of microwaveirradiation. To the best of our knowledge

A series of novel 5‐amino‐1,2,3‐triazole derivatives has been synthesized by combining a dipolar azide−nitrile cycloaddition with a Dimroth rearrangement undersolvent‐freeconditions. Solvent‐free approach for the synthesis of 5‐amino‐1,2,3‐triazoles is reported for the first time.

corresponding azides by the diazotization method, but the diazo transfer on the conjugate bases with tosyl azide proceeds smoothly and was used in this work as a general method to obtain the azides . The latter thermolyze by two different pathways, depending on the nature of the R4-substituent; i.e. rearrangement to diazoester substituted tetrazoles when R4 = COOR, and decomposition to alkylidenetriazenes
