The gas-phase reaction of bare Fe+ atoms with linear alkyl nitriles generates "end-on" complexes (1) which, depending on geometrical constraints, specifically interact with remote C-H bonds. Based on chain length effect studies and the investigation of labeled precursors, a mechanism is suggested which accounts for the chemospecificity observed for the loss of H2 and C2H4 from RCN/Fe+ complexes. This mechanism does not follow the analogous reaction of Fe+ with alkenes and alkynes but involves an initial C-H insertion of the remote CH bonds followed by a C-C insertion.
