PART A: The energies of a series of monosubstitued propane, cyclopropane and cyclopropene compounds were calculated using ab initio molecular orbital calculations optimized at the 3-21G level using Gaussian 82 and Gaussian 86 programs. The effects of substituents on stabilization energies and geometries are rationalized with respect to the parent molecules. The result is presented which indicated that for substituted cyclopropyl and cyclopropenyl compounds, most of the substituents induce stabilization except the —NC substituent group is destabilizing in cyclopropyl and cyclopropenyl systems. Indications of relative electrostatic and resonance effects are also analyzed. A linear free energy relationship has been exam-ined by comparing the stabilization energies and appropriate Taft Dual Substituent Parameter equation substituent constants: σI (induction effect) and sR (resonance effect).

PART B: The synthesis of 6,6,7,7-Tetramethy1-1-azabicyclo[2.2.2] octan-2-one (6,6,7,7-tetramethy1-2-quinuclidone) was done by Dr. Wu Guanli. Some kinetic data are obtained using conditions from a paper by Pracejus and co-workers. FTIR was em¬ployed to monitor the rate of decomposition which was then compared with others, less sterically-hindered, guinuclidone derivatives.
