[(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 (3.321Å) Mo-Mo bonding. Reaction of 2·PPN2 with sulfur gave the completely decarbonylated product [(C2B9H11)Mo(μ-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( μ-S)(O)]2PPN2 (4·PPN2). The structures of 3·PPN2 and 4·PPN2 were also studied.
