Research Interests:
Students in my group undertake research projects that fall under
the area of physical organic chemistry. Research in this area
focuses on the elucidation and understanding of structure - reactivity
relationships, intrinsic barriers, and reaction mechanisms. For
example, my current research efforts involve kinetic studies of
nucleophilic addition to alpha,beta-unsaturated compounds such
as alpha,beta-unsaturated ketones, lactones as well as alpha,beta-unsaturated
transition metal carbene complexes. We utilize a variety of kinetic
methods, including stopped- flow spectrophotometry for monitoring
fast reactions as well as conventional UV-Vis spectroscopy for
slower reactions. Students in my group also gain valuable synthetic
experience in that the synthesis of the target compounds involve
reactions learned in their undergraduate organic courses, like
the Aldol condensation and enamine chemistry. The synthesis of
the alpha,beta-unsaturated organometallic complexes require the
students gain experience in handling air senstive compounds such
as n-butyllithium, methyllithium and phenyllithium.
Our group has recently begun studying the above reactions from
a more theoretical point of view. In particular, we are using
PC Spartan Pro to investigate equilibrium geometries of the abovementioned
compounds. Equilibrium geometries can provide potential insight
into the importance and extent of resonance development in these
systems. Students involved in these computational studies learn
to use a variety of theoretical models, including Semi-Empirical,
Hartree-Fock, and Density Funtional Theory.
