First Sublimation Thermodynamics and First Gas‐Phase Experimental Molecular Structure of Heteroporphyrins: 5,10,15,20‐Tetraphenyl‐21‐X, 23‐Y‐Porphyrins (X=O or S; Y=N or S)

“…Hemoglobin, chlorophyll, Cofactor F430 and vitamin B 12 include the porphyrins (P) and their Fe(II)P, MgP, NiP and CoP complexes and find various applications in human activities. Effective catalytic applications were discovered for porous polymeric metal complexes of porphyrin in reaction of cycloaddition CO 2 with epoxide, [1] as catalysts for electrochemical reduction of O 2 and oxidation of H 2 O [2] . Metals play a key role in a central cavity and in a possibility to form a secondary coordination sphere [3] .…”

Fe(III)-Anchored Porphyrin-Based Nanoporous Covalent Organic Frameworks for Green Synthesis of Cyclic Carbonates from Olefins and CO2 under Atmospheric Pressure Conditions

“…The gradual increase in the atmospheric CO 2 concentration has resulted in climate change, a rise in global average temperature, and other potentially harmful environmental issues. − Toward contending this rise in atmospheric CO 2 levels, its selective capture/storage and utilization has been studied by researchers worldwide. Especially, carbon capture and its subsequent utilization as a C1 source for generating useful chemicals/fuels is a promising and valuable approach with the dual benefits of lowering atmospheric carbon dioxide concentration and producing commodity chemicals. − In this direction, various strategies have been employed by researchers in functionalizing CO 2 , a greenhouse gas, into valuable compounds. − Particularly, the transformation of CO 2 to cyclic carbonates (CCs) via cycloaddition reactions with epoxides is of much interest owing to its 100% atom efficiency. − Additionally, CCs find applications as polar solvents, electrolytes, and commodity chemicals for polymers. − Various strategies have been employed by researchers in developing catalytic systems for efficient coupling of CO 2 to epoxides for CC production. − However, the synthesis of CCs by a green, one-pot oxidative carboxylation of olefins is highly preferred over the two-step process involving the utilization of epoxides.…”
