Nickel-Catalyzed Reductive Cross-Coupling of N-Acyl and N-Sulfonyl Benzotriazoles with Diverse Nitro Compounds: Rapid Access to Amides and Sulfonamides
Herein we report a Ni-catalyzed reductive transamidation of conveniently available N-acyl benzotriazoles with alkyl, alkenyl, and aryl nitro compounds, which afforded various amides with good yields and a broad substrate scope. The same catalytic reaction conditions were also applicable for N-sulfonyl benzotriazoles, which could undergo smooth reductive coupling with nitroarenes and nitroalkanes to afford the corresponding sulfonamides.
A new and concise way to enamides by fluoroalkanosulfonyl fluoride mediated Beckmann rearrangement of α,β-unsaturated ketoximes
The reaction of α,β-unsaturated ketoximes with fluoroalkanosulfonyl fluorides in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) underwent the Beckmann rearrangement smoothly to afford the corresponding acid-sensitive enamides in moderate to excellent yields, which provides a new efficient method for the preparation of acid-sensitive enamides.

Nickel catalyzed addition of -NH- containing compounds to vinyl and aryl halides
A process for producing unsaturated nitrogen containing compounds such as enamides, enamines and aryl amines/amides is disclosed. A vinyl halide or aryl halide is reacted with an -NH- containing compound in the presence of a catalytic amount of a catalyst precursor composition comprising zero-valent nickel and an organophosphine ligand. One step coupling of vinyl halides and aryl halides with -NH- containing compounds is made possible by practice of this invention.
