1951Industr. & Engin. Chem. Feb. 387 The kinetic parameters deduced support a nonchain proton transfer mechanism, deprotonation being rate-determining. 1974D. Nicholls Inorg. Complexes iv. 38 In absolute ethanol, complexes undergo deprotonation just as in the case of water, and alkoxides (rather than hydroxides) are formed. 2001Chemicals & Materials from Renewable Resources ((ACS Symp. Ser. No. 784)) iv. 44 The first pathway would involve deprotonation of levulinic acid..at the C5-position. |
