The directdecarboxylativearylation of α-amino acids has been achieved via visible light-mediated photoredoxcatalysis. This method offers rapid entry to prevalent benzylic amine architectures from an abundant biomass, specifically α-amino acid precursors. Significant substrate scope is observed with respect to both the amino acid and arene components.

Nonactivated alcohols along with arene compounds are used in electrochemical dehydroxylative arylation for constructing C(sp3)–C(sp2) bonds. The PIII reagent undergoes single-electron anodic oxidation to form its radical cation, which reacts with the alcohol to produce an alkoxytriphenylphosphine radical. Through spontaneous β-scission of the phosphoranyl radical, the C–O bond is cleaved to form an
