This M.S. Thesis research objective is designed towards the racemic synthesis of a novel diastereoselectively pure, sterically bulky, cyclopropyl-containing, N-heterocyclic carbene (NHC) ligand. It is hypothesized that introduction of the sterically bulky cyclopropyl moiety at the N-substituent position of the imidazolium backbone will cause the self-assembly to develop a well defined C2-symmetric N-heterocyclic ligand, thereby limiting the free rotation about the C-N bond and creating a well-defined chiral pocket. It was discovered through utilizing classic synthetic methods that a diastereomeric imidazolium salt product was yielded, which can be attributed to the racemic synthesis of a diastereomeric cyclopropane starting material.
