| Summary: | Isocyanides insertions represent an important transformation in the palladium-catalyzed reactions landscape. However, one of their most significant limitations is in the use of inactivated alkyl electrophiles. Palladium photocatalysis has been proven as a solid tool for the generation of alkyl radicals from alkyl halides, which may engage in subsequent transformations with a variety of reaction partners, closing the catalytic cycle. Herein, we report the mild three-component isocyanide insertions into inactivated alkyl iodides mediated by the catalytic activity of a photoexcited palladium complex. We investigated the scope of the reaction obtaining differently substituted secondary amides in good to high yields. We also investigated the mechanism, hypothesizing a key role of 4-(<i>N</i>,<i>N</i>-dimethylamino)pyridine in the outcome of the reaction. |
