| ΔrH° (kJ/mol) | Method | Reference | Comment |
|---|---|---|---|
| 129.7 ± 4.2 | KinS | Lott, Chagovetz, et al., 1995 | solvent: Ethylene glycol; The reaction refers to "base-on" cobalamine.; MS |
| 125.5 ± 8.4 | KinS | Waddington and Finke, 1993 | solvent: Ethylene glycol; The reaction enthalpy relies on 144.3 ± 3.3 kJ/mol for the reaction activation enthalpy. The reaction refers to "base-on" cobalamine.; MS |
| 125. | KinS | Hay and Finke, 1986 | solvent: Water; The reaction enthalpy relies on the activation enthalpy for the reaction, 138.1 ± 8.4 kJ/mol Hay and Finke, 1986, and on an estimated activation barrier for the fragment recombination, ca. 13. ± 4. kJ/mol Hay and Finke, 1986. The reaction refers to "base-on" cobalamine.; MS |
| 131. | KinS | Finke and Hay, 1984 | solvent: Ethylene glycol; The reaction enthalpy relies on the activation enthalpy for the reaction, 144.3 ± 3.3 kJ/mol Finke and Hay, 1984, and on an estimated activation barrier for the fragment recombination, ca. 13. ± 4. kJ/mol Finke and Hay, 1984. The reaction refers to "base-on" cobalamine.; MS |
| <144.3 ± 3.3 | KinS | Finke and Hay, 1984 | solvent: Ethylene glycol; Please also see Hay and Finke, 1988. The value represents an upper limit to the reaction enthalpy, since it is the activation enthalpy for the Co-C bond cleavage. The correction (i.e. the activation enthalpy for the reverse process, the fragment recombination reaction) depends on the solvent and leads to a range of reaction enthalpy values: 126 to 144. kJ/mol Hay and Finke, 1988. The reaction refers to "base-on" cobalamine.; MS; Data excluded from overall average |
| 109. ± 8. | KinS | Halpern, Kim, et al., 1984 | solvent: Water; The reaction enthalpy relies on the activation enthalpy for the reaction, 119.7 ± 4.2 kJ/mol Halpern, Kim, et al., 1984, and on an estimated activation barrier for the fragment recombination, ca. 11. kJ/mol Halpern, Kim, et al., 1984. The reaction refers to "base-on" cobalamine.; MS |
