Abstract
Photo-oxidation of $Re_{2}$(CO)$_{10}$ in low-temperature matrices containing $O_{2}$ generates alongside free CO and $CO_{2}$, the binary oxide $Re_{2}$$O_{7}$. The reaction appears to be initiated by Re-Re bond cleavage and proceeds via at least two detectable oxorhenium carbonyl species. Infrared spectroscopic studies, including isotopic studies with $^{18}O$ and $^{13}CO$, suggest that these intermediates are most likely to be $(CO)_{5} Re-C-O-Re(CO)_{5}$ and $O=Re(CO)_{5}$. Similar photo-oxidation experiments have also been carried out on the compounds $Re(CO)_{5}Cl, Re(CO)_{5}Me$ and $CpRe(CO)_{3}$. The last two compounds appear to give rise to the organometalic oxides $MeReO_{3}$ and $CpReO_{3}$.
