<br/>Rhodium (I) based catalysts are used actively in industry to efficiently hydrogenate unsaturated compounds, such as alkenes and alkynes. These types of organometallic catalysts are well-known and studied compounds, however, minimal research has been completed with regard to their electrochemical properties and that of their analogues. Primarily, this research project focuses on synthesizing a number of rhodium (I) analogues with various electron donating and electron withdrawing substituents. Preparations of the analogues are practiced utilizing Schlenk-line (air- and moisture-free) techniques. Following synthesis, the compounds were checked for purity and extent of reaction completion using infrared (IR) spectroscopy and nuclear magnetic resonance (NMR). Cyclic voltammetry (CV), a type of electrochemical technique, was used to find the substances’ oxidation and reduction potentials. The potentials of the analogues differed based on the given substituent. Spectroelectrochemical experiments were also used to assess structural changes upon oxidation.
