Previously there has been no high yielding synthesis of Re(CO)4LX (L = Group 15 donor ligand, X = Cl, Br, I).We here show that the PdO-catalysed reaction between Re(CO)5X and L gives Re(CO)4LX in > 75percent yield when L has a cone angle less than 150 deg.The new complexes have been fully characterised by IR and 1H NMR spectroscopy.
