Abstract

In the photochemical reactions of triplets of both protoporphyrin-IX-dimethyl-ester (PP) and haematoporphyrin dihydrochloride (HP) with α-phenyl-ethyl hydroperoxide (HROOH) in C6H6 at room temperature, both OO and CC bonds are broken yielding alkoxy and carbon-centred radicals. The ruptures of CC and OH bonds were observed in the photochemical reaction of PP with tert-butanol in the same solvent, yielding alkoxy and carbon-centred radicals at λ≥ 366 nm, while HP did not react photochemically with tert-butanol at λ≥334 nm.
