Abstract
AbstractIn the present study we have, synthesized silver nanoparticles supported on carbon nitride AgNPs@g‐C3N4 and investigated its catalytic aspects by using microwave. We found that silver nanoparticles supported on g‐C3N4 were highly active in the A3‐coupling reaction of (Aldehyde, secondary amine and terminal alkynes) for the synthesis of propargylamines with excellent yield up to 97% and in C−C coupling reaction of terminal alkynes for the synthesis of 1, 3‐diyne with excellent yield up to 98%. We have achieved excellent TON (72932), TOF (3636 min−1), E‐factor (0.27) and atom economy AE (94%). Reaction parameters like effect of catalyst quantity, effect of time and effect of temperature was deeply studied. The catalyst was characterized by SEM, HR‐TEM, EDX, XRD, ICP‐AES and IR.
