Hirai, Takahiro published the artcileEsterification of Tertiary Amides: Remarkable Additive Effects of Potassium Alkoxides for Generating Hetero Manganese-Potassium Dinuclear Active Species, Quality Control of 5961-59-1, the main research area is esterification tertiary amide potassium alkoxide manganese dinuclear catalyst; amides; esterification; manganese; reaction intermediates; reaction mechanisms.
A catalyst system of mononuclear manganese precursor combined with potassium alkoxide served as a superior catalyst compared with our previously reported manganese homodinuclear catalyst (defined within) for esterification of not only tertiary aryl amides, but also tertiary aliphatic amides. On the basis of stoichiometric reactions of a manganese precursor and potassium alkoxide salt, kinetic studies, and d. functional theory (DFT) calculations, we clarified a plausible reaction mechanism in which in situ generated manganese-potassium heterodinuclear species cooperatively activates the carbonyl moiety of the amide and the OH moiety of the alcs. We also revealed details of the reaction mechanism of our previous manganese homodinuclear system, and we found that the activation free energy (ΔG≠) for the manganese-potassium heterodinuclear complex catalyzed esterification of amides is lower than that for the manganese homodinuclear system, which was consistent with the exptl. results. We further applied our catalyst system to deprotect the acetyl moiety of primary and secondary amines.
