Abstract
In this paper the reactions of iron(II) hydrides 6–10 formed by selective CF/CH bond activation in fluoroaryl-imines were reported. Iron hydrides 6 and 7 reacted with haloalkane to give rise to the corresponding iron halides 11 and 12 with the mer-rearrangement of the three trimethylphosphine ligands. The related trifluoromethylcarboxyl iron complexes 13 and 14 with the carboxyl group as monodentate ligand were obtained from the reactions of hydrides 8 and 9 with F3CCOOH. The reaction of iron hydride 6 with Lewis acid LiBF4 delivered ionic iron complex 15. Both the reaction of iron hydride 10 with Me3SiCCH and the reaction of iron bromide 11 with Me3SiCCLi could provide the derivative trimethylsilylacetylenyl iron(II) complexes 16 and 17 respectively. The molecular structures of complexes 12, 13 and 17 were determined by single crystal X-ray diffraction.
