A novel phenol-linked bis(imidazolium) salt,H3LCl2(L = O-4-C(CH3)3-C6H2-2,6-di[CH2{C(NCHCHNAr)}]2, Ar = 2,6-diisopropylphenyl, 1), was designed and used to prepare an ionic iron(III) complex [H2L][Fe Cl4](2).Complex 2 was a highly efficient catalyst for aryl Grignard cross-coupling of alkyl chlorides bearing b-hydrogens.Furthermore, complex 2 was reusable and could be reused in at least eight times without significant loss in catalytic activity.
