Notizen:
Gas-phase experiments on the Fe+-mediated oxidation of 2-propanol and ethanol by 1,3-butadiene are described. The reaction takes place at an atomic Fe+ centre, and labeling experiments uncover its specificity. While the gas-phase reaction of Fe(η4-C4H6)+ with 2-propanol occurs at collision-rate and the analysis of ligand-binding energies, in principle, favour a catalytic cycle for the Fe+-mediated dehydrogenation of 2-propanol by 1,3-butadiene, this conjecture is not born out experimentally due to complicating “side” processes. In addition to the specific interligand two-hydrogen-atom transfer from the alcohol to butadiene, the study of isotopomers reveals several hydrogen-exchange processes preceding dehydrogenation, dehydration, and alkene loss from (C4H6)Fe+ (alcohol) complexes.
