Alteration of the Reactivity of a Tellurophene Within a Core‐Modified Porphyrin Environment: Synthesis and Oxidation of 21‐Telluraporphyrin

Abstract

A pyrrole ring of a porphyrin as an intramolecular proton donor: compound 1 (depicted below), with a deprotonated pyrrole ring, has been isolated as an intermediate in the oxidative transformation of the corresponding air-sensitive 21-telluraporphyrin into 21-oxaporphyrin.
