Notes:
The reactions of the metal dicarbonyl anion Fe(CO)2- with methanol and five of its isotopomers, namely CD3OH, CH3OD, CD3OH and CH318OH have been studied by the use of Fourier-transform ion cyclotron resonance mass spectrometry. Three competitive reaction channels have been identified in these trapped-ion/molecule studies which, for methanol, lead to the formation of three primary reaction products, namely [HFe(CO)(OCH)3]- formed in a decarbonylation channel; Fe(CO)3- in a channel involving C—H and O—H bond activations and bis-dehydrogenation of a collision complex; and also [(CH2O)Fe(CO)2]- in a separate channel involving the elimination of a single H2 molecule. The primary product ion [HFe(CO)(OCH)3]- further reacts with methanol to give a bis-alkoxy substituted metal carbonyl ion [(CH3O)2Fe(CO)]- at trapping times of several seconds. Complex deuterium isotope effects of an interactive nature with respect to the three reaction channels also have been observed.
