“…Acetals are also suggested to be a potential dehydrating agent for this reaction, due to its low price and the aldehyde formed by hydrolysis is easily reconverted to acetal [116]. Choi et al [123] observed that the performance of DMP as dehydrating agent can be improved by the addition of ammonium triflates (Tf : CF 3 SO 3 -) as acid co-catalyst, such as [Ph 2 NH 2 ]OTf. In addition, DMC yield increased from 17 % to 40 % in the presence of ammonium triflates at 453 K and 30 MPa.…”

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.

“…Acetals (e.g., 2,2 -dimethoxypropane , DMP ) are also good candidates for chemical water trapping, invariably leading to an increase in the turnover number s ( TON s) [55 -57] . Interestingly, the coaddition of trifl ate salts to n -Bu 2 SnO (Sn : trifl ate = 10) caused a signifi cant improvement in the TON, from 4 up to 10, at 453 K under 30 MPa for 24 h [58] . One drawback of chemical trapping is that either a substituted urea (from DCC) or acetone (from DMP) are coproduced.…”

The synthesis, X-ray structure, spectroscopic and catalytic properties of sterically hindered Schiff-base ligands (L 1 H = N-[allylamine]-3,5-di-tert-butyl salicylaldimine, L 2 H=N-[2-amino-5-methyl pyridine]-3,5-di-tert-butyl salicylaldimine and L 3 H=N-[2-amino-6-methyl pyridine]-3,5-di-tert-butyl salicylaldimine), and their mononuclear Cu(II) complex for L 1 H with multinuclear Cu(II) complexes for L 2 H and L 3 H, were described. The copper(II) complexes of these ligands were synthesized by treating an methanolic solution of the appropriate ligand with an appropriate amount of CuCl 2 Á2H 2 O. The ligands and their copper(II) complexes were characterized by FT-IR, UV-Vis, 1 H-NMR, elemental analysis, measurement of room temperature magnetic moment, and X-ray structural determination. The reaction of the L 2 H and L 3 H ligands in a 1:1 mol ratio with CuCl 2
