Visible-light, photoredox catalyzed, oxidative hydroxylation of arylboronic acids using a metal–organic framework containing tetrakis(carboxyphenyl)porphyrin groups

A Zr-based metal-organic framework with tetrakis(carboxyphenyl)porphyrin groups (Zr-MOF-TCPP: MOF-525) has been utilized as a photoredox catalyst to promote oxidative hydroxylation of arylboronic acids under green LED light irradiation. Zr-MOF-TCPP displays a superior catalytic activity for this process over the corresponding homogeneous catalyst (H4TCPP).
