The reaction of 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene (IPr) with one equivalent of a novel imidazolium salt of iron(II), [FeBr3(C4H8O)](HIPr)center dot C4H8O (1), afforded the anionic iron( 11) complex bearing an N-heterocyclic carbene ligand [Fe(IPr)Br-3](HIPr)center dot C7H8 (2), which shows extremely high activity in comparison with the other iron(II)-based precatalysts in the cross-coupling reaction of 4-tolylmagnesium bromide with cyclohexyl bromide.
