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

J Am Chem Soc. 2002 Apr 17;124(15):3838-9. doi: 10.1021/ja017852z.

Abstract

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 eta(2) Cd(II)-arene interaction.
