dc.description.abstract | The specific rates of the solvolyses of methyl fluoroformate (CH3OCOF) and ethyl fluoroformate (CH3CH2OCOF) in pure and several hydroxylic solvents have been measured at 40.0°C and 24.2°C using the titrimetric method. The extended Grunwald-Winstein equation has been applied to the solvolyses of methyl fluoroformate and ethyl fluoroformate. Analyses of the data using the extended Grunwald-Winstein equation to the specific rates of the solvolyses of methyl fluoroformate and ethyl fluoroformate lead to sensitivities toward changes in solvent nucleophilicity (l) of 1.33±0.09 and toward changes in solvent ionizing power (m) of 0.73±0.06, and to sensitivities toward changes in solvent nucleophilicity (l) of 1.34±0.14 and toward changes in solvent ionizing power of (m) 0.77±0.07, respectively. For four and five representative solvents, studies were made at several temperatures and activation parameters determined. For methanolysis, a solvent deuterium isotope effect of MeOH/MeOD is compatible with the incorporation of general-base catalysis into the substitution process. In conclusion, the solvolyses of methyl fluoroformate and ethyl fluoroformate are indicated to proceed by a bimolecular addition-elimination pathway in pure and several hydroxylic solvents considered. These observations are also compared with those previously reported for the corresponding chloroformate and fluoroformate esters. | - |
