“…It is noteworthy to mention that CO 2 is moderately reactive, abundant and renewable source of carbon to be employed as C1 building block for the synthesis of a wide range of fuels and value added fine chemicals or intermediates . These CO 2 utilization or fixation reactions can be broadly classified into three categories, i) CO 2 reduction to CO, CH 3 OH, CH 4 , HCHO, HCO 2 H or higher hydrocarbons, ii) reactions involving new C−C, C−O, C−N bond formations and iii) synthesis of organic and inorganic carbamates, cyclic carbonates or polycarbonates . A wide range of porous nanomaterials including PMO bearing basic urea containing moiety (PMO‐UDF), Zn‐containing SBA‐15 material impregnated with potassium iodide, tri‐s‐triazine containing ionic liquid, etc.…”

To overcome the challenges of global warming and environmental pollution it is mandatory to reduce the concentration of atmospheric carbon dioxide (CO2), which is largely accumulated in air through the combustion of fossil fuels. Thus, sequestration of CO2 through physisorption on solid adsorbents and their successful conversion into value added fine chemicals are the major priority areas of research today. Innovation of efficient solid CO2‐philic adsorbents together with their high mechanical/chemical stability and regeneration efficiency are the most challenging objectives to achieve this goal. In this context, porous organic polymers (POPs) owing to their high specific surface area, chemical stability, nanoscale porosity and structural diversity have huge potential to play as selective CO2 adsorbent. POPs synthesized through large varieties of reactive monomers via simple and convenient chemical routes can be the ideal adsorbents for the CO2 storage and fixation reactions. A wide range of POPs can be synthesized from different multidentate amines, aldehydes, carboxylic acids or triazine monomers through the polycondensation reactions or solid state condensation reactions. Ease of synthesis, uniform pore width together with high surface area and surface basic sites (nitrogen and other heteroelements) play crucial role in the CO2 absorption and conversion reactions. This review provides a concise account in designing POPs and their application in CO2 adsorption and fixation into reactive organic molecules for the synthesis of fuels and value added fine chemicals.

“…[9a] We have decorated Ag NPs at the surface of ap orous metal-organic frameworks and the resulting AgNPs@CO-MOF heterogeneous catalyst showed very good catalytic activity and recyclability for the carboxylation of av ariety of terminal alkynes to yield alkyne carboxylates. [82] Here the MOF nanostructure could stabilize Ag NPs of 4.5 AE 0.3 nm size, which could activate the alkyne CÀHb ond and thus insertion of CO 2 molecules could proceed smoothly. Direct fixation of CO 2 onto aryl halides from the respective benzylic alcohols/aldehydes is very challenging.P dN Ps decorated on N-doped mesoporous carbon materials synthesized through the pyrolysis of glucoseand melamine in the presence of non-ionic surfactant showed good catalytic activity for the synthesis of benzyl alcohols from aryl iodides and CO 2 under moderate pressure.…”

“…Ag NPs supported over an N‐heterocyclic carbene (NHC) polymer can be utilized as an efficient catalyst for the carboxylation of terminal alkynes using CO 2 as C1 source .

Metallic nanoparticles in the presence of base could activate the terminal alkynes to their respective metal acetylides (Ag/Cu).…”

CO is a major greenhouse gas responsible for global warming and can act as an abundant and inexpensive C1 source for enhancing the chain length/functionalization of a wide range of reactive organic molecules. It is moderately reactive, nontoxic and renewable. Thus, CO fixation reactions are important to meet the global challenges, that is, to mitigate the concentration of CO in the atmosphere through its fruitful utilization, which is of great interest from economic and environmental perspectives. Various metallic nanoparticles as well as metal oxides can be supported over high surface area porous materials and the resulting nanomaterial can act as heterogeneous and reusable solid catalyst for CO fixation reactions for the synthesis of a large number of fuels, natural products agrochemicals, and pharmaceutical compounds. Here we present an overview of the recent progress as well as promising future of metal/metal oxide nanoparticles supported over porous nanomaterials as heterogeneous catalysts for a wide spectrum of these CO fixation reactions.

This review focuses on recent advances in the field of direct carboxylation reactions of C(sp 3 )-H and C(sp 2 )-H bonds using CO 2 encompassing both transition-metal-catalysis and base-mediated approach. The review is not intended to be comprehensive, but aims to analyze representative examples from the literature, including transition-metal catalyzed carboxylation of benzylic and allylic C(sp 3 )-H functionalities using CO 2 which is at a "nascent stage". Examples of light-driven carboxylation reactions of unactivated C(sp 3 )-H bonds are also considered. Concerning C(sp 3 )-H and C(sp 2 )-H deprotonation reactions mediated by bases with subsequent carboxylation of the carbon nucleophile, few examples of catalytic processes are reported in the literature. In spite of this, several examples of base-promoted reactions integrating "base recycling" or "base regeneration (through electrosynthesis)" steps have been reported. Representative examples of synthetically efficient, base-promoted processes are included in the review.
