Mild and direct intramolecular oxidative aryltrifluoromethylations of activated alkenes have been established through visible light photocatalysis, affording a range of CF3-containing oxindoles or isoquinolinediones in the presence of an organic fluorophore-type photocatalyst 4CzIPN, oxygen and visible light irradiation under strong oxidant and transition metal free conditions. A variety of frequently
The radical reactions of N-(2-halogenoalkanoyl)-substitutedanilines (anilides) of type 1 have been investigated under various conditions. Treatment of compounds 1a–1o with Bu3SnH in the presence of (2,2′-azobis(isobutyronitrile) (AIBN) afforded a mixture of the indolones (oxindoles) 2a–2o and the reduction products 5a–5o (Table 1). In contrast, the N-unsubstituted anilides 1p–1s, 1u, and 1v gave the
