Popis: | The reactions of gas-phase Fe + with n-pentanenitrile and several deuterium-labeled isotopomers have been studied together with low-energy collision-induced dissociation (CID) of Fe(C 4 H 9 CN) + complexes, employing Fourier transform ion cyclotron resonance (FTICR) spectrometry. While loss of H 2 is due to remote functionalization, ethylene is produced from internal positions, generating CH 3 -Fe + -CH 2 CN, an isomer of Fe(CH 3 CH 2 CN) + . Loss of propene is also observed in low abundance, producing an iron-acetonitrile complex. All three processes are in competition with the formation of a ferracyclobutane complex, which, upon reopening, brings about equilibration of the α and (ω-1) position, thus affording a specific, degenerate isomerization of the Fe(C 4 H 9 CN) + collision complex. Collision-induced dissociation experiments with isotopomeric reaction products were performed, which provided structural information and revealed the positions of the deuterium atoms after the degenerate isomerization |
