Abstract

The new complex Os{1,3-(iPr2PCH2)2 C6H3}(Cl)(PPh3) (2) was obtained from the reaction between the diphosphine {1,3-(iPr2 PCH2)2C6H4} (1) and OsCl2(PPh3)3. 2 reacts with H2 to yield the dihydrido species Os{1,3-(iPr2 PCH2)2C6H3}(H)2(Cl) (PPh3) (3). Addition of 1 equiv of carbon monoxide to 2 led to the formation of Os{1,3-(iPr2PCH2)2 C6H3}(CO)(Cl)(PPh3) (4), while in the presence of excess CO, the bis-carbonyl complex Os{1,3-(iPr2PCH2)2C6 H3}(CO)2-(Cl) (5) was formed. Both 2 and 5 were structurally characterized by X-ray diffraction studies. The reaction of OsCl2(PPh3)3 (under hydrogen pressure) and OsHCl(PPh3)3 with the diphosphine {1,3,5-(CH3)3-2,6-(iPr2 PCH2)2C6H} (6) led to the formation of the C-C activation products Os{3,5-(CH3)-2,6-(iPr2 PCH2)2C6H}(H2)(Cl)(PPh3) (7) and Os{3,5-(CH3)-2,6-(iPr2 PCH2)2C6H}(Cl)(PPh3) (8), respectively.
