Carbon-hydrogen bond activation remote

The activation of intramolecular carbon-hydrogen bonds by metal ions in the gas phase first involves tt-coordination, followed by remote functionalization of C—H or C—C several carbons distant from the initial coordination site. Schwarz has reviewed his prolithic work in this area. High-resolution translational energy loss measurements on the remote functionalization of internal alkynes by Cr" have been made. These indicate that the ions involved are in the ground state and that no added collisional energy transfer is needed for cyclometallation to proceed. The reactions of Fe", Co", and/or Ni" have been studied with alkyl-substituted amines, " alcohols, ketones, nitriles, " ... [Pg.271]
