ABSTRACT
Harnessing radical intermediates in regioselective reactions presents a substantial challenge. Here, we report novel control strategy through engineering covalently tethered transition metal-photocatalysts that conjoin Pd-phosphine and Ru/Ir photoredox units. This allows us to override the innate regioselectivity of Pd-catalysed C-H allenylation N-aryl tetrahydroisoquinolines.
