Individual Reactions

C12H7MnO5 (g) = C5MnO5 (g) + Benzyl radical (g)

By formula: C12H7MnO5 (g) = C5MnO5 (g) + C7H7 (g)

Quantity Value Units Method Reference Comment
Δr32.3 ± 4.5kcal/molICR/PESMartinho Simões, Schultz, et al., 1985Please also see Martinho Simões and Beauchamp, 1990. The reaction enthalpy was derived from the appearance energy of Mn(CO)5(+), 198.3 ± 4.6 kcal/mol, using Mn(CO)5(Bz) as the neutral precursor, together with the adiabatic ionization energy of Bz radical, 166.0 ± 0.45 kcal/mol Martinho Simões, Schultz, et al., 1985. The enthalpy of formation relies on -153.6 ± 2.2 kcal/mol for the enthalpy of formation of Mn(CO)5(Bz)(g)
