Terphenyl Derivatives of d-Block and Group 12 Elements

Terphenyl ligands have also been utilized in the context of metalloporph-yrin chemistry. For example, the use of four Triph substituents at the periphery of manganese and iron porphyrin derivatives dramatically in- 

The only other known transition metal terphenyl derivative is the blue, crystalline cobalt species Co(ju.-Br)C6H3-2,6-Mes2(THF) 239 (Fig. 12). It is isostructural to the corresponding magnesium derivative discussed earlier. It was synthesized via the reaction of CoCl2 with the Grignard reagent,
