Modifying Diruthenium Paddlewheel Compounds via Ligand Exchange Reactions
Abstract
Due to problems arising from continued use of fossil fuels, the need for CO2 reduction catalysts and sulfide oxidation catalysts has grown. Selective reduction of carbon dioxide to a product that could be incorporated into another fuel would slow the increase of CO2 in the atmosphere. Additionally, residual sulfides in fossil fuels can lead to sulfur in the atmosphere which falls out as acid rain. In an effort to design a catalyst for CO2 reduction or sulfide oxidation, diruthenium paddlewheels were modified. Diruthenium paddlewheel complexes have the ability to exist in many different oxidation states which makes them well suited for catalysis. Starting materials of the type Ru 2(DArF)3(OAc)Cl and Ru2(DArF)2(OAc) 2Cl were modified via salt metathesis. A side product of the reaction between Ru2(DmAniF)3(OAc)Cl and K 2CO3 was studied along with the main product of the reaction between Ru2(D(3,5-Cl2Ph)F)2(OAc)2Cl and etidronic acid: Na[Ru2(D(3,5-Cl2Ph)F)2(hedp)].
