dc.description.abstract | DFT calculations were used to determine the structures and energies of bicyclobutane and oxabicyclobutane as valence isomers derived from electronic excitation of their corresponding precursors, 1,3-butadiene and acrolein, respectively. Proton affinities of these strained compounds were determined and compared with their simple ring components, cyclopropane and ethylene oxide. The basicity as determined from proton affinities showed that bicyclobutane is the most basic saturated hydrocarbon, even more basic than oxabicyclobutane. Strain energies of these valence tautomers were computed which showed oxabicyclobutane to be significantly more strained than bicyclobutane. Qualitative reasons are provided to account for the difference in strain energies. | en_US |
