Abstract
The enthalpies of formation (#x0394;H°f) of twenty-one amidyl radical (R•) belonging to the formamidyl homological series were calculated using the published values of R—H bond dissociation energies. Among them, the ΔH°f values of nine radicals were first calculated and those of eight radicals were refined. Most of the ΔH°f values of corresponding starting molecules RH (ΔH°f(RH)) were obtained using the macroincrementing schemes. Based on the group additivity scheme, the “structure—enthalpy of formation” relationships for the radicals considered were examined, the ΔH°f(R•) values were analyzed, and their reliability was confirmed. Parameters for calculating the ΔH°f values of radicals belonging to this homologous series were suggested.
