Hydroarylation of alkenes has been demonstrated to be an atom-economic approach to access functionalized arenes from easily accessible raw materials. Herein, we report a visible light-induced photocatalytic system that enables intramolecular hydroarylation of N-arylacrylamides with high 5-exo-trig selectivity through robust proton-coupled electron transfer (PCET). This mild hydroarylation protocol provides a straightforward entry to structurally valuable oxindoles and complements previously established 6-endo-trig cyclization by photochemical triplet energy transfer (TET).

This paper reports two new visible-light-promoted radical reactions of α-azido amides. By catalysis of [Ir(ppy)2(dtbbpy)]PF6 with i-Pr2NEt as the reducing agent, N-aryl α-azido tertiary amides were first converted to the corresponding aminyl radicals through reduction of the azido group; the aminyl radicals then underwent N-to-N aryl migration to give α-anilinyl-functionalized amides. α-Azido secondary amides, on the other hand, reacted with the solvent ethanol and i-Pr2NEt to afford the imidazolinone products.

(Equation presented) Thermolysis of α-alkoxyamino propionanilides produces indolinones, whereas thermal reaction of N-allylaniline derivatives with various Tordo-type alkoxyamines results in formation of indolines in the radical regime.
