An unusual oxidative coupling reaction of isocyanide and toluene derivatives using tetrabutylammonium iodide (TBAI) as a catalyst is disclosed. The experimental results and mechanistic study show that the isocyano group acts formally as an N1 synthon during the transformation, thus expanding the reactivity profile of isocyanide.

wide substrate scope is reported. Benzamides with electron‐donating and ‐withdrawing groups and linear, branched, and cyclic alkyl azides are all applicable. Cesium carboxylate is crucial for both reactivity and regioselectivity of the reactions. Many biologically relevant molecules, such as amino acid, peptide, steroid, sugar, and thymidine derivatives can be introduced to arenes with high yields and

CH activation: The ruthenium‐catalyzed direct sp2 CHamidation of arenes by using sulfonyl azides as the amino source is presented (see scheme). A wide range of substrates were readily amidated including arenes bearing weakly coordinating groups. Synthetic utility of the thus obtained products was demonstrated in the preparation of biologically active heterocycles.

Mechanochemical conditions have been applied to an iridium(III)‐catalyzed C−H bond amidation process for the first time. In the absence of solvent, the mechanochemical activation enables the formation of an iridium species that catalyzes the ortho‐selective amidation of benzamides with sulfonyl azides as the nitrogen source. As the reaction proceeds in the absence of organic solvents without external

A fast and efficient mechanochemicalRitterreaction between alcohols and nitriles under mild conditions is demonstrated. The reaction proceeds rapidly at roomtemperature in a solvent-free or low-solvent environment, utilizing a Bronsted acid catalyst. Its general application has been verified through a substrate screening investigation comprising a wide range of functionalized nitriles, as well as
