| Transition metal complexes are attractive candidates for catalyzing reactions because of their tendency to undergo two-electron changes in oxidation state. However, the outer-sphere electron-transfer reactions of these complexes are often irreversible, and this behavior can prevent regeneration of the active catalyst and completion of the catalytic cycle. In an effort to overcome this problem and better understand the factors controlling cooperative redox processes, we are investigating several strategies for designing metal complexes that will undergo cooperative, outer-sphere and reversible two-electron transfer. The approach relies on the preparation of metal complexes with dangling nucleophilic groups that can stabilize the square planar coordination geometry preferred by a metal center having a d8 electron configuration and the octahedral geometry of a metal center having a d6 electron configuration. We will discuss the synthesis, structures and reactivity of new two-electron platinum reagents and the role of the ligands in tuning the reactivity. |
