Abstract

D-block metals show great promise in inorganic catalytic research. Particularly, copper has contributed to the catalytic properties of pincer complexes. Copper complexes were obtained through attachment of copper (I) to tridentate di-pyrazole-3,6-di-tert-butyl-carbazole, a N,N,N-pincer ligand. This ligand changes the metal geometry, affecting reactivity. We used lithium di-isopropyl amide to deprotonate the ligand and reacted it with copper (I) chloride to obtain complexes 1 and 2. Upon acquiring NMR spectra and X-ray crystal structures, oxidation studies gave structures 3-5. Using complexes 1-5, electron transfer rate studies were performed to display the differences in electron transfer rates between the complexes.
