Catalysis plays a great role in the world today with one of the most prominent industries being the polymers industry. Linear alpha olefins (LAO’s) are short to long chain carbon molecules whose uses range from plastics to motor oils to synthetic lubricants. This project aims to develop a ligand that can direct a metal complex to selectively catalyze the formation of lucrative short chain linear alpha olefins from ethylene.1-5 The target ligand is an asymmetric tridentate ligand that uses phosphorus, carbon, and nitrogen to bind to the transition metal of choice and features a benzimidazole backbone. This ligand design is a continuation of research initiated in Dr. Carney’s group at UWEC.6,7 After synthesis and characterization of this ligand, the obtained organometallic complex is anticipated to function as an effective catalyst. Presented here are the synthetic steps of this project to obtain the free pre-ligand along with a crystal structure of a precursor molecule. This synthesis utilizes a combination of open-to-air and air-sensitive techniques. Future work is planned to complete the synthesis of the metal complex and test the catalytic ability for the selective formation of the desired LAO’s.
