His design employs either polyesters (more sustainable due to access to bio-based raw materials) or poly-imides (for high-temperature applications) that are functionalized with cyclobutane
substrates through the photochemistry of maleic anhydrides, which undergo a [2[Plus]2] cycloaddition reaction to form cyclobutanes
when exposed to one wavelength of light and the reverse when exposed to another.
11:30 CONVENTIONAL STRAIN ENERGY OF DIMETHYLSUBSTITUTED CYCLOBUTANES AND THE GEM-DIMETHYL EFFECT
Comparisons are made between the conventional strain energy of cyclopropane and cyclobutane, methylcyclobutane, and the dimethyl-substituted cyclobutanes.
Finally, the calculated strain energies are compared to those of cyclopropane, cyclobutane, azetidine, phosphetane, 1,2-oxazetidine, and 1,3-oxazetidine.
Finally, the calculated strain energies are compared to those of cyclopropane, cyclobutane, oxaziridine, azetidine, phosphetane, diazetidine, and diphosphetane.
