Preparation and spectral properties of the new mixed complexes (MI/sub 2/(CO)/sub 3/(py)L) (M = Mo and W; L = PPh/sub 3/, AsPh/sub 3/ and SbPh/sub 3/)
Seven-coordinate complexes of molybdenum(II) and tungsten(II) have become increasingly important as homogeneous catalysts. For example, the complexes (MX/sub 7/(CO)/sub 3/L/sub 2/) (M = Mo and W; X = Cl and Br; L = PPh/sub 3/ and AsPh/sub 3/) have been shown to be catalysts for the ring-opening polymerization of norbornene. Although a wide variety of complexes of the type (MX/sub 2/(CO)/sub 3/L/sub 2/) (M = Mo and W; X = Cl, Br and I; L = nitrogen, phosphorus, arsenic and antimony donor ligands)/sub 2/ have been reported, until now no examples of the mixed complexes (MX/sub 2/(CO)/sub 3/(py)L) have been prepared. In this communication the authors wish to describe the synthesis of the new mixed pyridine/L compounds (MI/sub 2/(CO)/sub 3/(py)L) (M = Mo and W; L = PPh/sub 3/, AsPh/sub 3/ and SbPh/sub 3/).
