Synthesis of 1,2,3 triazole-linked pyrimidines catalyzed by mg-Al-LDH-immobilized-CuI as a heterogeneous catalyst

A useful and efficient procedure was obtained for the synthesis of 1,2,3-triazole-linked pyrimidines via click reaction of propynylated pyrimidine and aromatic azides in the presence of Mg-Al-LDH-immobilized-CuI with high-to-excellent yields. Moreover, the prepared catalyst was characterized by the FT-IR spectroscopy, XRD, BET, SEM, and ICP techniques. The developed synthetic technique offers numerous advantages such as a clean reaction, easy workup, high reaction yields, and short reaction time.
