Tetraphenyl-p-benziporphyrin: A carbaporphyrinoid with two linked carbon atoms in the coordination core

Article abstract of DOI:10.1021/ja017852z

Replacement of one of the pyrrole rings with a p-phenylene unit transforms porphyrin into p-benziporphyrin (1), an aromatic carbaporphyrinoid that locates two connected carbon atoms in the coordination core. p-Benziporphyrin forms a complex with cadmium(II) (2) with an unprecedented η² Cd(II)-arene interaction.
