This study focuses on the reactions of Fe{sup +} with several monosubstituted benzene derivatives in the gas phase utilizing Fourier transform mass spectrometry techniques and laser desorption generation of iron ions. Generally, the phenyl group is not directly involved in the reactions, although the formation of the benzyne ligand (C{sub 6}H{sub 4}) was commonly observed. Only in one case (nitrobenzene) was the benzene C{sub 6} skeleton altered and the formation of the C{sub 5}H{sub 5} ligand observed. The initial step in the reactions of the iron ions usually involves insertion into a bond to the most electronegative atom in the substituent group. Insertions into C-C and C-H bonds were also observed, and hydrogen or methyl group shifts often preceded bond cleavage.
