We report a rare polarity-mismatched radical addition reactionusing styrene boronic acids and redox-active N-hydroxyphthalimide (NHPI) esters under photoredox catalysis. The reactiondisplays broad scope with mechanistic investigations supporting a unique synergistic activation pathway that displays chemoselectivity for styrene boronic acids in the presence of other SOMOphiles.
