Toyao, Takashi published the artcileEsterification of Tertiary Amides by Alcohols Through C-N Bond Cleavage over CeO2, Related Products of esters-buliding-blocks, the main research area is tertiary amide aliphatic alc reusable cerium dioxide nanocatalyst esterification; ester preparation green chem.
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.
