Thermochemical Studies of Epoxides and Related Compounds
Gas-phase
heats of formation for the four butene oxide isomers are reported.
They were obtained by measuring the condensed-phase heat of reduction
to the corresponding alcohol using reaction calorimetry. Heats of
vaporization were determined and allow gas-phase heats of formation
to be obtained. The experimental measurements are compared to calculations
obtained using a variety of computational methods. Overall, the G3
and CBS-APNO methods agree quite well with the experimental data.
The influence of alkyl substituents on epoxide stability is discussed.
Comparisons to alkenes, cyclopropanes, aziridines, thiiranes, and
phosphiranes are also made. Isodesmic-type reactions were used to
determine strain energies of the epoxides and related compounds with
various substituents
