The introduction of chlorinated porphyrin ‌18‌ allows for hydrogen peroxide to be used as terminal oxidant.[‌78‌] This catalyst has been demonstrated to resist decomposition, and, when used together with imidazole or imidazolium carboxylates as additives, efficient epoxidation of alkenes is achieved (‌Table 4‌, entries 1, 2).
