“…ε L ≈ 0, then Equation (3) can be used to calculate the formation constant. (3) The values of the adduct formation constants (Table 4) are calculated by fitting of experimental absorbance data to Equation (2) or (3). Figure 3 shows the change in the absorption spectrum upon successive addition of MTO to a ligand solution in CH 2 Cl 2 .…”

“…The latter group discovered the ability of MTO to act as a versatile catalyst of various organic reactions. [3] MTO can be used in several catalytic processes, for instance olefin metathesis [4] and aldehyde olefination. [5] Most recently, MTO has been successfully applied in deoxygenation of epoxides.…”

A series of chromophoric Lewis base adducts of methyltrioxorhenium (MTO) was examined. The ligands were pyridine derivatives with different size of the aromatic system and variable substituents, thus providing a variation of electronic and steric parameters. The complexes were fully characterised (UV/Vis, IR and NMR spectroscopy, single-crystal X-ray diffraction and elemental analysis) and their stability constants in dichloromethane were determined by means of UV/Vis spectroscopy. Moreover, this report presents a study of the influence of these N-donor ligands coordinated to MTO on the catalytic activity of epoxidation of 1-octene.

“…The halflife of hydrogen peroxide is 20 000 times higher in the presence of MTO than in that of RuCl 3 , and 50 times higher than in the presence of MnO 2 [99]. Upon treatment of MTO with hydrogen peroxide a rapid equilibrium takes place as shown in Scheme 6.11.…”

“…Methyltrioxorhenium (MTO) is a well-known catalyst used in several oxidation reactions [37]. In a way to improve the immobilization of MTO in ILs, Saladino et al [38] reported the synthesis of catalysts based on the heterogenization of MTO on poly(4-vinylpyridine) and poly(4-vinylpyridine N-oxide) (Fig.…”

Ionic Liquids (ILs) in Organometallic Catalysis

Ionic liquids (ILs) have attracted the scientific community due to several advantages compared with traditional solvents such as their low volatility and high ability to dissolve different organic and inorganic compounds, among other advantages. Transition metals can be toxic compounds; however, this issue can be minimized when used in catalytic amounts which also allows reaction efficiency and selectivity increases. The combination of metal catalysis with the use of ILs can be a powerful tool for several organic reactions, taking advantage of the most attractive property of the ILs, which is the possibility of an easier recycling of the catalytic system, increasing the greenness of the process. The application of ILs in metal-catalyzed oxidation reactions of alcohols and sulfides is discussed in this chapter.
