In 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.

氮化碳支持的银纳米粒子：丙炔胺的微波辅助合成和氧化性C-C偶联反应

在本研究中，我们合成了负载在氮化碳AgNPs @ g-C ₃ N ₄上的银纳米颗粒，并通过微波研究了其催化作用。我们发现载于g‐C ₃ N ₄上的银纳米颗粒在（醛，仲胺和末端炔烃）的A ³偶联反应中对炔丙基胺的合成具有很高的活性，产率高达97％，并且在C–C中末端炔烃的偶联反应可合成1，3-二炔，产率高达98％。我们已经获得了出色的TON（72932），TOF（3636 min ^-1），E系数（0.27）和原子经济AE（94％）。对催化剂数量，时间和温度的影响等反应参数进行了深入研究。通过SEM，HR-TEM，EDX，XRD，ICP-AES和IR对催化剂进行了表征。
