A visible-light-induced and iron-catalyzed methylation of arylacrylamides by dimethyl sulphoxide (DMSO) is achieved, leading to 3-ethyl-3-methyl indolin-2-ones in high yields. This reaction tolerates a series of functional groups, such as methoxy, trifluoromethyl, cyano, nitro, acetyl and ethyloxy carbonyl groups. The visible-light promoted radical methylation and arylation of the alkenyl group are

Photoinduced hydroarylation of alkenes is an appealing synthetic strategy for arene functionalization. Herein, we demonstrated that aryl radicals generated from electron‐deficient aryl chlorides/bromides could be trapped by an array of terminal/internal aryl alkenes in the presence of [Pt(O^N^C^N)] under visible‐light (410 nm) irradiation, affording anti‐Markovnikov hydroarylated compounds in up to
烯烃的光诱导加氢芳基化是芳烃官能化的一种有吸引力的合成策略。在此,我们证明了在可见光下,[Pt(O ^ N ^ C ^ N)]存在下,电子不足的芳基氯化物/溴化物产生的芳基自由基可能被一系列末端/内部芳基烯烃捕获(410)。纳米)辐射,以高达95%的收率提供抗马氏化学水解的化合物。此外,还开发了一种用于[Pt(O ^ N ^ C ^ N)]催化的丙烯酰胺分子内光环化反应的化合物,以提供结构多样的3,4-二氢喹啉酮。

While the reductive ketyl couplings of carbonyls have been widely explored, we report in this work on a redox-neutral umpolung carbonyl coupling reaction through ketyl radical formation by consecutive photoinduced electron transfer (ConPET) under metal- and additive-free conditions. The donor–acceptor cyanoarene-based fluorophore, 1,2,3,5-tetrakis(carbazol-9-yl)-4,6-dicyanobenzene (4CzIPN), was used
