Photocatalytic Redox-Neutral and Reductive Deoxygenative Alkylation of Benzyl Alcohols Using <i>N</i>-Acyl Carbamothioates as Radical Precursors

Herein, we report a photocatalytic redox-neutral and reductive deoxygenative alkylation of <i>N</i>-acyl carbamothioates from benzylic alcohols, with substituted Hantzsch esters and allylic sulfones to afford unsymmetrical 1,2-diaryl ethanes and allylarylmethanes, respectively. This protocol facilitates facile deoxyalkylation of primary, secondary, and tertiary benzylic alcohol-derived <i>N</i>-acyl carbamothioates, which features mild reaction conditions, broad functional group tolerance, and the obviation of external S/O trapping reagents as well as transition metal-coupling catalysts.
