The recent advancement on the tailored synthesis of hypercrosslinked microporous polymer (HMP‐2) has assembled significant concentration by the virtue of its adjustable porosity, operative design and absolutely ordering structure. This perfectly structured Ag NPs supported carbocatalyst (Ag‐HMP‐2) has been synthesized by Friedel‐Crafts alkylation between 4,4′‐Bis(bromomethyl)‐1,1′‐biphenyl and carbazole over anhydrous iron(III)chloride catalysis followed by the appending of the silver nanoparticles (Ag NPs) onto the material. The silver nanoparticle was decorated over the HMP‐2 to prepare the corresponding catalyst (Ag‐HMP‐2). The characterization of the newly produced material has been conducted by N 2 adsorption/desorption studies, XPS, FE‐SEM, transmission electron microscopy (TEM) and Powder X‐ray diffraction (PXRD) methods. This microporous catalyst has spectacular activities for the production of tetramic acids from various types of propargylic amine derivatives at 60 °C under atmospheric carbon dioxide pressure. Parallel attempt on fixation of CO 2 was executed over terminal alkynes to synthesize propiolic acids under 1 atm pressure. The catalyst (Ag‐HMP‐2) exhibited sufficient recycling ability for the generation of tetramic acids and propiolic acids up to five catalytic runs without reduction in its catalytic activity.
