The standard molar enthalpies of combustion and formation of 2-methylbenzothiazole, 2-methylbenzoxazole, and 2-methyl-2-thiazoline

Interplay of thermochemistry and structural chemistry, the journal (volume 24, 2013, issues 5–6) and the discipline

“…The reader will note that the thermochemistry of 2-methylbenzoxazole is discussed in both the current paper and that of Flores et al [136]. At this point, it remains unclear why the two sets of results for this species, studied as the liquid, have enthalpies of formation, which differ by roughly 30 kJ mol -1 .…”

“…The energies of combustion of 2-methylbenzothiazole, 2-methylbenzoxazole, and 2-methyl-2-thiazoline were experimentally determined, and the liquid-phase standard molar enthalpies of formation (T = 298.15 K) were derived by Flores et al [136]. Comparison with the enthalpy of formation of the acyclic N,S-dimethylthioacetimidate (formed by C-C bond ring cleavage in the thiazoline) is welcomed.…”
