Bimetallic Hydroformylation Catalysis: In Situ IR and NMR Spectroscopic Studies

In Situ FT-IR and NMR spectroscopic studies on an active and regioselective bimetallic hydroformylation catalyst are presented. The studies shed new light on the species actually present under catalytic conditions. A revised bimetallic hydroformylation mechanism involving cationic bimetallic catalyst species is presented.
