Abstract:
1,1'-Bis(4-(2-hydroxy-3,5-di-tert-butylphenyl)aminophenyl)ferrocene (pFlipH4) is prepared in three steps from commercially available 1,1'-ferrocenediboronic acid or its pinacol ester. The suitability of the ligand to bind as a tetradentate ligand in a cis, planar fashion has been confirmed by formation of a square planar palladium bis-iminosemiquinone (pFlip)Pd. The linker unit appears to be structurally similar to 1,1'-ferrocenediyl, but the electronic interaction of the ferrocene with the aminophenols is minimal.

In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
