Oxidative Alkylation of tetrakis(4-Hydroxyaryl)porphyrins

Research output: Contribution to conferencePoster


The attempted O-benzylation of tetrakis(3,5-bis(t-butyl)-4-hydroxyphenyl)porphyrin gave a product which was clearly having a different structure than expected. NMR, UV, X-ray and MS spectral analysis showed that it corresponded to a N-tetraalkylated oxidized product, having a tetrakis(quinomethide) structure. The reaction conditions were optimized to influence the degree and regioselectivity of this reaction with different alkylation reagents.
