【 摘 要 】

[(C₂B₉H₁₁)Mo(CO)₃]₂PPN₂ (2·PPN₂), a new precursor for the oxidative decarbonylation reaction, was synthesized in high yield by the one-electron oxidation reaction of [(C₂B₉H₁₁)Mo(CO)₃]PPN₂. 2·PPN₂ was structurally characterized, showing a dimeric nature with long (3.321�?) Mo-Mo bonding. Reaction of 2·PPN₂ with sulfur gave the completely decarbonylated product [(C₂B₉H₁₁)Mo(�?-S)(S)]₂PPN₂ (3·PPN₂). The ligand substitution of the terminal sulfur ligands in 3·PPN₂ to oxygen ligands was carried out with the use of PhIO to give [(C₂B₉H₁₁)Mo( �?-S)(O)]₂PPN₂ (4·PPN₂). The structures of 3·PPN₂ and 4·PPN₂ were also studied.
