“…3). This has been demonstrated for carbonylations and hydroformylations amongst other examples [36,37]. Alternatively the low polarity of carbon dioxide and some other supercritical fluid solvents can be exploited to cause an anti-solvent effect and allow for substrates to be precipitated from solution, before returning the liquid solvent to a reusable state ( Fig.…”

“…Other olefins have also been used. So, for example norbornene and allylbromide have been coupled in presence of CO 2 to afford double functionalised norbornane or functionalized condensed cycles . Aromatic carboxylic acid is obtained starting from aromatics under mild conditions (Equation ) with 85% conversion.…”

CO2 is considered to play a key role in an eventual climate change, due to its accumulation in the atmosphere. The control of its emission represents a challenging task that requires new ideas and new technologies. The use of perennial energy sources and renewable fuels instead of fossil fuels and the conversion of CO2 into useful products are receiving increased attention. The utilization of CO2 as a raw material for the synthesis of chemicals and fuels is an area in which scientists and industrialists are much involved: the implementation of such technology on a large scale would allow a change from a linear use of fossil carbon to its cyclic use, mimicking Nature. In this paper the use of CO2 as building block is discussed. CO2 can replace toxic species such as phosgene in low energy processes, or can be used as source of carbon for the synthesis of energy products. The reactions with dihydrogen, alcohols, epoxides, amines, olefins, dienes, and other unsaturated hydrocarbons are discussed, under various reaction conditions, using metal systems or enzymes as catalysts. The formation of products such as formic acid and its esters, formamides, methanol, dimethyl carbonate, alkylene carbonates, carbamic acid esters, lactones, carboxylic acids, and polycarbonates, is described. The factors that have limited so far the conversion of large volumes of CO2 are analyzed and options for large‐scale CO2 catalytic conversion into chemicals and fuels are discussed. Both homogeneous and heterogeneous catalysts are considered and the pros and cons of their use highlighted. © 2013 Society of Chemical Industry

The modern refinery relies primarily on feedstocks based on fossil fuels (such as petroleum, natural gas, and coal) to produce fuels and chemicals. Several megaton catalytic processes (such as homogeneous hydroformylation of higher olefins, epoxidation of light olefins, and p-xylene oxidation to produce terephthalic acid) exist that produce the essential chemical intermediates for everyday products but present sustainability challenges with respect to reducing environmental footprints and enhancing energy efficiency. Meeting the increasing demand for such chemicals, through either fossil-based feedstock or plant-based biomass, will require the development of novel sustainable processes. This article highlights the role and promise of neoteric solvents such as compressed CO2, ionic liquids, and water, with an emphasis on gas-expanded liquids (GXLs), for the development of sustainable catalytic processes and the challenges thereof. It is also shown that chemical reaction engineering is the critical link to bring the promise of green chemistry to the marketplace.

Versatile chemoselectivity in Ni-catalyzed multiple bond carbonylations and cyclocarbonylations in CO2-expanded liquids

Abstract: Selective mono or double carbonylations could be achieved by using CO(2)-expanded liquids in [2 + 2 + 1] carbonylative reactions of alkenes or acetylenes with allyl bromides catalyzed by Ni(i).
