title: Formation of dodecaphenylporphodimethene via facile protonation of saddle-distorted dodecaphenylporphyrin.
abstract: A saddle-distorted dodecaphenylporphyrin undergoes protonation followed by two-electron reduction by SnCl(2) to give a roof-shaped dodecaphenylporphodimethene which exhibits reversible one-electron reduction and oxidation behaviour in benzonitrile to allow us to observe an ESR spectrum of pi-cation radical in the course of electrochemical oxidation.
