- Abstract
Herein, we report the efficient synthesis of copper(II) phthalocyanines in the presence of DBU as a strong base. These synthesized copper(II) phthalocyanines are utilized as a catalyst for the click reactions of sensitive compounds including metal-free porphyrins under mild reaction conditions at room temperature. Further, we have developed a one-pot procedure for the click reactions of benzyl halides with different alkynes in good to excellent yields. The reaction proceeds at room temperature to 40 °C and gives 83–99% of products. The reactions are carried out in DMSO solvent. The present reaction condition offers copper(II) phthalocyanines as an efficient and convenient catalyst for different electron-rich and electron-deficient substrates including macrocyclic compounds. Electron-deficient substrates and less steric substrates provide a better result. The catalyst is easily separated from the reaction by a simple filtration technique and is reused up to 5 times without significant loss of its catalytic activity.
