A new method was developed to synthesize iodine-substituted Z-enamides through N-iodosuccinimide-mediated intermolecular iodofunctionalization of allenamides with indoles, pyrroles, and furans. These reactions proceed rapidly and tolerate a broad scope of substrates. The conjugated sulfimide ion species probably acts as the key intermediate.

The thermal decomposition of toluene-p-sulphonyl azide (1) in an excess of benzene under a nitrogen atmosphere gave p-tosyl-1H-azepine (2), the yield of which increased with an increase in N2 pressure.
Ligand-Controlled Regiodivergence for Catalytic Stereoselective Semireduction of Allenamides

Ligand-controlled regiodivergence has been developed for catalytic semireduction of allenamides with excellent chemo- and stereocontrol. This system also provides an example of catalytic regiodivergent semireduction of allenes for the first time. The divergence of the semireduction is enabled by ligand switch with the same palladium pre-catalyst under operationally simple and mild conditions. Monodentate ligand XPhos exclusively promotes selective 1,2-semireduction to afford allylic amides, while bidentate ligand BINAP completely switched the regioselectivity to 2,3-semireduction, producing (E)-enamide derivatives.

Paragraph 0031-0049, (2021/06/13)
The invention provides a quantum dot and a method for preparing a sulfonamide derivative by using the quantum dot, and belongs to the technical field of preparation of benzenesulfonamide carbocyclic compounds. According to the method, sulfydryl aromatic hydrocarbon is taken as an initial raw material, nitro aromatic hydrocarbon is taken as a nitrogen source, CdSe/3CdS core/shell quantum dots are taken as a photocatalyst, reaction is carried out under visible light irradiation, a target product with high yield is obtained, and the quantum dot catalyst can be recycled. The synthesis process is green, convenient to operate, low in raw material price and easy to obtain, and suitable for large-scale industrial production.
