IRON CARBONYLS-CYCLOALKENES

[(1,3-Butadiene)(toluene)Fe(0)]

[(1,3-cyclohexadiene)(toluene)Fe(0)]

    [(1,3-Butadiene)(toluene)Fe(0)] (1) and [(1,3-cyclohexadiene)(toluene)Fe(0)] (2) were synthesized by metal vapor synthesis. They were characterized by their vapor pressure at different temperatures and their decomposition behavior

      Both complexes [(1,3-Butadiene)(toluene)Fe(0)] and [(1,3-cyclohexadiene)(toluene)Fe(0)] were applied as MOCVD precursors for the growth of thin Fe films on alumina powders at moderate temperatures (T < 200 °C) in a fluidized bed reactor (FB-MOCVD), for potential application as iron metal catalysts and characterized by various methods like ICP OES, SEM/EDX, particle size analysis, H2/TPR and CO adsorption. The iron layer of the samples grown by FB-MOCVD formed homogeneously surface-distributed nanocrystals, which were much smaller in size and had a higher dispersion , compared to conventionally prepared iron catalysts. Therefore the FBMOCVD prepared  nanocrystals were much more redox processes-reactive and adsorb ~40% more CO, thus representing a higher catalytic activity.[i]
