ChemInform Abstract: PHOTOCHEMISTRY OF SOME BINUCLEAR CARBONYL COMPOUNDS OF MANGANESE, RHENIUM, MOLYBDENUM, AND TUNGSTEN, AND OF SOME RELATED PENTACARBONYLMETAL HALIDES IN N-DONOR SOLVENTS

On irradiation in solvents of high donicity, the binuclear carbonyl compounds [M2(CO)10](M = Mn or Re) and [{M(η-C5H5)(CO)3}2](M = MO or W) undergo efficient photoheterolysis leading to a metal carbonyl anion; related carbonylmetal halides [M(CO)5X](M = Mn or Re, X = Cl, Br, or I) on similar treatment also give rise to the corresponding carbonyl anion.
