| Abstract: | The reactions of the tungsten(I) complex of picolinic acid W(CO)3(pic)]n with certain monodentate tertiary phosphines affords a convenient route to complexes of the types W(CO)3(PR3)3 and HW(CO)2(PR3)2(pic). The latter hydrido complexes of tungsten(II) have been characterized by infrared and NMR spectroscopy. The reactions of Re2(CO)10 with picolinic acid have also been investigated and the new series of rhenium(I) derivatives of the types Re(CO)3(L)(pic), where L = py, 4-Ph-py, PPh3 or dppe, and Re(CO)2(L')2(pic), where L' = PPh3 or dppe, have been isolated and characterized. |
