“Green” replacements for platinum group metals (PGMs) have been of considerable interest in the catalysis community. Within the larger field of sustainable catalysis, the use of potentially redox non-innocent (RNI) ligands in conjunction with Earth-abundant 3d metals to mimic PGM catalytic cycles has been the intensely studied. Our group has sought to develop the intellectual advances necessary to understand (and design) catalyst systems whereby a RNI ligand and a 3d metal may be synergized to deliver 2 <i>e<sup>-</sup></i> to a metal-ligand active site for the purposes of productive catalytic reactions such as the activation and functionalization of strong chemical bonds. In addition to elaborately constructed organic supporting ligand scaffolds, our recent research, in concert with experimental efforts, shows evidence of RNI behavior in unexpected chemical moieties including multiply bonded ligands and even saturated, ring-strained hydrocarbyls.
