Microwave assisted azide-alkyne cycloaddition reaction using polymer supported Cu(I) as a catalytic species: a solventless approach

A polymer supported copper(I) composite has been synthesized using a one-step chemical synthesis route under ambient conditions. The resultant material serves as an effective catalyst for a 1,3-dipolar cycloaddition reaction between terminal alkynes and azides to synthesize 1,2,3-triazoles with excellent yields using a microwave irradiation technique in the absence of any solvent. The composite has also been found to be an effective catalyst for the multicomponent synthesis of 1,2,3-triazoles from organic halides, sodium azide and terminal alkynes under the identical conditions as mentioned above.
