Abstract

PM3 and DFT calculations have been performed with complete optimization of geometries on cyclohexanone, cyclopentanone, and acetone. The enol content trend determined in this work was cyclohexanone > cyclopentanone > acetone, which was found to agree with published experimental and theoretical works. Equilibrium constants, strain energies of enols, and electron distributions are reported.
