CeO2 was found to promote ester forming alcoholysis reactions of tertiary amides. The present catalytic system was operationally simple, recyclable and it does not require additives. The esterification process displayed a wide substrate scope (>45 examples; up to 93 % isolated yield). Results of a d. functional theory (DFT) study combined with in-situ FT-IR observations indicated that the process proceeded through rate limiting addition of a CeO2 lattice oxygen to the carbonyl group of the adsorbed acetamide species with energy barrier of 17.0 kcal/mol. This value matched well with exptl. value (17.9 kcal/mol) obtained from anal. of the Arrhenius plot. Further studies by in-situ FT-IR and temperature programmed desorption using probe mols. demonstrated that both acidic and basic properties were important and consequently, CeO2 showed the best performance for the C-N bond cleavage reaction. This study involved multiple reactions and reactants, such as 2-Ethylhexyl benzoate (cas: 5444-75-7Recommanded Product: 5444-75-7).
2-Ethylhexyl benzoate (cas: 5444-75-7) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Recommanded Product: 5444-75-7
