The Sonochemistry of Some Metal Carbonyl Complexes (Iron, Chromium)
… sonochemical reactions. Sonication of iron pentacarbonyl, neat or in hydrocarbon solvents, produces triiron dodecacarbonyl and finely divided iron powder. The ratio of these products may be varied by changing the vapor pressure of the solvent. The mechanism for formation of triiron dodecacarbonyl …

Synthesis and characterisation of mononuclear and dinuclear rhenium carbonyl complexes
… ligands and the corresponding rhenium(I) tricarbonyl. The structure of the complexes have been determined using NMR and IR spectroscopy. The complexes underwent [Re—>7t*(pyridyl-triazole)] transitions in the 295 - 360 nm region of the absorption spectrum. Emission was observed from all the …

Carbonyl ylide cycloadditions of dicobalt carbonyl complexes of propargylic aldehydes
The intermolecular, three-component carbonyl ylide cycloaddition of a diazo compound, aldehyde, and carbon-carbon multiple bond is a powerful method to construct five-membered oxygen heterocycles. An adjacent dicobalt hexacarbonyl cluster permits the expansion of the scope of this process to …

The synthesis, characterization, and reactivities of iron carbonyl complexes containing bismuth or antimony
When (Et$\sb4$N) $\sb3$(Bi$\{$Fe(CO)$\sb4\}\sb4$) is treated with main group metal halides complicated disproportionation reactions occur. The reaction with BiCl$\sb3$ in MeCN yields (Et$\sb4$N) (BiFe$\sb3$(CO)$\sb{10}$), (Et$\sb4$N) $\sb2$(Bi$\sb2$Fe$\sb4$(CO)$\sb{13}$), and (Et$\sb4$N) …
