The catalytically active complex in the homogeneously catalyzed, regioselective hydroformylation is possibly the dinuclear complex dication 1 . The 1 J (Rh,H) coupling constant of 164 Hz is the largest such value ever reported and may be a distinctive marker for dinuclear Rh II complexes with terminal hydrido ligands.
