Methylimidazole complexes

Aida and Jiang recently reported an iron(II) porphyrin 1-methylimidazole complex covalently encapsulated within a large aryl ethereal dendrimer cage, as... 

Although the kinetics of imidazole exchange between NP2 and its low-spin imidazole adduct are very slow and no chemical exchange cross peaks in the NOESY/EXSY spectrum of a mixture of the high-spin and low-spin forms of NP2 are observed, the V-methylimidazole complex... 

The dimethylimidazolate and the methylimidazolate complexes undergo a chemically reversible two-electron oxidation in dichloromethane at the same potential value E° (0/2- -) = -fO.56 V), which demonstrates the lack of interaction between the two ferrocenyl centers of these species. Nevertheless, if one considers that free...
