A highly porous, crystalline catechol porphyrin COF was synthesized and applied as an organocatalyst for the chemicalfixation of carbondioxide to synthesize value-added chemicals such as cyclic carbonates and oxazolidinones under solvent-free and transition-metal-free conditions. The high surface area and the functionalities of the COF catalyst act synergistically to activate the starting material

activity of N‐heterocyclic olefins (NHOs) as a newly emerging class of organocatalyst is investigated for the chemical fixation of carbondioxide through reactions with aziridines to form oxazolidinones and the N‐formylation of amines with polymethylhydrosiloxane (PMHS) or 9‐borabicyclo[3.3.1]nonane (9‐BBN) as the reducing agent under mild conditions. The exocyclic carbon atoms of NHOs are highly nucleophilic
