Herein we reported a protocol to access aminated benzofused sultams through sequential ortho‐amination, followed by ipso‐arylation of aryl iodide bearing sulfonamide functional group via palladium/norbornene coorperative catalysis. This reaction has showcased a broad spectrum of substrate scope under mild conditions with moderate to good efficiency.

Herein, a nickel-catalyzed two-component reductive arylcyanation of aryl (pseudo)halide tethered alkenes using benzyl thiocyanate as a cyanide source via C–S bond activation is developed.

Herein, we report a palladium/norbornene/copper co-catalyzed single-step approach that merges selective ortho CÀ H bond esterification with ipso thiolation for construction of synthetically versatile 2-arylthio aryl esters under exceptionally mild conditions. Importantly, this process proceeded in a highly efficient manner, allowing alkoxycarbonyl and thio groups to be installed into one aryl iodides simultaneously by harnessing thiocarbonate as bifunctional reagent. The method has been demonstrated to accommodate good functionalities and features broad substrate scope.

Herein, a three component Catellani-type reaction catalyzed by the Palladium/Norbornene/ CuI (Pd/NBE/CuI) cooperative system by using Nacylph-thalimides as acyl electrophiles is reported, which gives access to a series of aromatic ketones. The transformation is performable in the presence of water, albeit with decreased reaction yield. The additive CuI was crucial to facilitate the cleavage of C(O)À N bond of imide. This protocol showed broad substrate scope: both alkyl and aryl acyl groups could be installed at the ortho-position of aryl iodides; alkenes and boronic acids can be used as termination reagents.
