Article on the enthalpies of combustion of 2-iodosobenzoic acid and 4-nitrosophenol and the dissociation enthalpy of the I-O bond.

Notes
Abstract: The standard (p⁰ = 0.1 MPa) molar enthalpies of combustion in oxygen, at T = 298.15 K, for crystalline 2-iodosobenzoic acid, (OI)C₆H₄COOH, and 4-nitrosophenol, (ON)C₆H₄OH, were measured by rotating-bomb calorimetry and static-bomb calorimetry, respectively. These values were used to derive the standard molar enthalpies of formation of the crystalline compounds. An indirect method was used for assessing the dissociation enthalpy of the (I-O) bond in the iodoso derivative, D(m)⁰(I-O) / (kJ · mol⁻¹) = (264.5 ± 8.1), which is the first value reported for an iodine-oxygen bond in an organic molecule.
