“…They compared different Cu(I) precursors (Cu 2 O < CuCl < CuBr < CuI) and pointed out that the stronger the electronegativity of the anion in the additive, the weaker the promoting effect of the corresponding cuprous compound. Furthermore, they used this strategy to modify dibutyltin oxide [35] and found that Cu 2 O could significantly enhance its activity, with a conversion of dimethyl carbonate as high as 50.8% and a selectivity of transesterification reaching 99.9%. They attempted to explain these phenomena using the hard and soft acid-base theory, finding that the transesterification is a combination of soft bases and hard acids.…”

Diphenyl carbonate is one of the raw materials used for the synthesis of polycarbonate, and its green and clean production is of great importance to the non-phosgene process for polycarbonate. The production of diphenyl carbonate by transesterification is its representative process route and is considered to be one of the typical examples of a green and sustainable process for chemicals. Since the discovery of the transesterification catalyst for diphenyl carbonate in the 1970s, researchers have been committed to improving its catalytic activity and selectivity and, correspondingly, the reaction engineering process. However, thermodynamic limitations, low activity, low selectivity, and limited stability have been bottlenecks that the transesterification catalyst has not been able to completely overcome, and the improvement of the catalyst is still ongoing. Therefore, this review takes the transesterification reaction of dimethyl carbonate and phenol as a model reaction and, based on a review of the progress in catalyst research on catalytic reaction processes, tries to clarify the structure–activity relationship between catalytic active sites and catalytic performance in homogeneous and heterogeneous catalytic processes and provides an overview of the progress in catalyst synthesis and modification.

“…Among linear carbonates the most important are dimethylcarbonate (DMC), diphenylcarbonate (DPC) and diethylcarbonate (DEC). DMC is used in the chemical industry as monomer for polymers, in transesterification reactions for the production of other carbonates such as diphenylcarbonate and others, as alkylating or carboxylating agent . It is also used in the agrochemical and pharmaceutical industry for the production of chemicals or in product formulation.…”

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
