Highly Regioselective Ir-Catalyzed β-Borylation of Porphyrins via C−H Bond Activation and Construction of β−β-Linked Diporphyrin

Highly Regioselective Ir-Catalyzed β-Borylation of Porphyrins via C−H Bond Activation and Construction of β−β-Linked Diporphyrin

Highly regioselective borylation of 5,15-diaryl- and 5,10,15-triarylporphyrins has been achieved by the reaction with bis(pinacolato)diborane under iridium catalysis. Borylated porphyrins are a useful building block for constructing porphyrin arrays, hence offering an effective route to β-functional...

Zusammenfassung:Highly regioselective borylation of 5,15-diaryl- and 5,10,15-triarylporphyrins has been achieved by the reaction with bis(pinacolato)diborane under iridium catalysis. Borylated porphyrins are a useful building block for constructing porphyrin arrays, hence offering an effective route to β-functionalized porphyrins.
