Abstract
In this work, the reactivity of 2-nitro-5,10,15,20-tetraphenylporphyrin with 2-(4-nitrophenyl)acetonitrile in the presence of KOH as base was studied. Under these conditions, three new compounds were isolated: a β-di-substituted derivative, as the major compound, accompanied by two minor products, a π-extended and a β-isoxazoline-fused derivative, all in acceptable yields. A preliminary study was also performed in the presence of K2CO3. It allowed the isolation of a cyclopropyl-annulated chlorin in very good yield. All the obtained products were photochemically and photophysically characterized, some of them showing promising properties to be used as photosensitizers in photodynamic processes.Graphical abstract
