Available online xxxx a b s t r a c tThe present review covers organic transformations involved in the reduction of CO 2 to chemical fuels. In particular, we focus on reactions of CO 2 with organic molecules to yield carboxylic acid derivatives as a first step in CO 2 reduction reaction sequences. These biomimetic initial steps create opportunities for tandem electrochemical/chemical reductions. We draw parallels between long-standing knowledge of CO 2 reactivity from organic chemistry, organocatalysis, surface science and electrocatalysis. We point out some possible non-faradaic chemical reactions that may contribute to product distributions in the production of solar fuels from CO 2 . These reactions may be accelerated by thermal effects such as resistive heating and illumination.

CCDC no.: 1527333The asymmetric unit of the title crystal structure is shown in the figure. Tables 1 and 2 contain details on crystal structure and measurement conditions and a list of the atoms including atomic coordinates and displacement parameters. Source of materialThe title compound was synthesised by reaction of equimolar quantities of 4-methylaniline and dimethylcarbamoyl chloride in dichloromethane at 40°C for 1 h in the presence of excess triethylamine (1.38 mole equivalents). The crude product was recrystallized from a 1:3 mixture (by volume) of ethyl acetate and diethyl ether to give 1,1-dimethyl-3-(4-methylphenyl)urea (92%) as colourless crystals, Mp.

“…In fact, this sort of shuttling action has been proposed as part of the catalytic mechanism of a number of enzymes, [13][14][15] and is consistent with the proton conductivity properties of imidazole in the solid state where long H bonded chains are present. [16] Although the synthesize mechanism of C 4 H 8 N 2 O has been revealed with the catalyst of CeO 2 [17][18][19] , the catalytic of Mo-complex to synthesize imidazole ring with the reactants of 1,2-propanediamine (1,2-DPA) and CO 2 was rarely presented to date.…”
