“…In highly diluted methanol solutions at room temperature, 6 gives rise to the formation of the decakis(di-n-butyl (IV)) oxocluster, (n-Bu 2 SnO) 6 [(n-Bu 2 SnOR) 2 (CO 3 )] 2 (7), also characterized by single crystal X-ray diffraction analysis, and also isolated from carbonation recycling experiments [4c]. In parallel, to prevent the deactivation of active organotin(IV) intermediates by water, several groups have shown that the addition of chemical water-trap, such as acetals [10] and ortho esters [11], as well as the use of additives, such as tetramethoxysilanes [12] and triflates salts [13], could promote the regeneration of tin(IV) alkoxide species, leading to a catalytic system.…”

“…Under these conditions, the authors reached a conversion around 1 % and observed a decrease to half of the activity between the first and second reactions. The deactivation of dibutyltin dimethoxide with water can be overcome by the regeneration of Bu 2 SnO with methanol in the presence of a dehydrating alcohol, such as 2,2-dimethoxypropane (DMP), as proposed by Kohno et al [87], at high carbon dioxide pressure and excess of DMP. The effects of the dehydrating alcohol are discussed in depth in the next section.…”

This review summarizes the state-of-the-art for direct synthesis of dimethyl carbonate (DMC) from carbon dioxide and methanol. In addition, conventional and alternative processes are also discussed in order to understand the advantages and disadvantages of the direct synthesis of DMC. Furthermore, the major applications of DMC are described: solvent, fuels additive, and building block for organic synthesis. The major drawbacks of the direct synthesis of DMC are the low yield and reaction rate, mostly induced by the highly stable carbon dioxide molecules. The development of novel catalyst and strategies to enhance the DMC yield -such as dehydrating agents that remove the water from the reacting mixture -are pointed out as the key solution for this route. Therefore, the main catalysts (homogeneous and heterogeneous catalysts) used so far are presented, together with the respective operating conditions and catalyst performance. The use of different dehydrating agents to increase the DMC yield is also discussed.

Dedicated to Professor Heribert Offermanns on the occasion of his 75 th birthdayWith the growing perception of industrialized societies that fossil raw materials are limited resources, academic chemical research and chemical industry have started to introduce novel catalytic technologies which aim at the development of economically competitive processes relying much more strongly on the use of alternative carbon feedstocks. Great interest is given world-wide to carbon dioxide (CO 2 ) as it is part of the global carbon cycle, nontoxic, easily available in sufficient quantities anywhere in the industrialized world, and can be managed technically with ease, and at low cost. In principle carbon dioxide can be used to generate a large variety of synthetic products ranging from bulk chemicals like methanol and formic acid, through polymeric materials, to fine chemicals like aromatic acids useful in the pharmaceutical industry. Owing to the high thermodynamic stability of CO 2 , the energy constraints of chemical reactions have to be carefully analyzed to select promising processes. Furthermore, the high kinetic barriers for incorporation of CO 2 into C-H or C-C bond forming reactions require that any novel transformation of CO 2 must inevitably be associated with a novel catalytic technology. This short review comprises a selection of the most recent academic and industrial research developments mainly with regard to innovations in CO 2 chemistry in the field of homogeneous catalysis and processes.
