Abstract

Abstract The dipole moments of the title diketones have been measured and compared with the values calculated by MM2. Both sets of values are in good agreement. The diketones exist (74–94%) in pairs of enantiomeric conformations with angles between both carbonyl dipoles in the range 62–66°.
