Liu, Jiangjun published the artcileNickel-Catalyzed Intramolecular Desulfitative C-N Coupling: A Synthesis of Aromatic Amines, Synthetic Route of 258278-25-0, the publication is Journal of Organic Chemistry (2020), 85(8), 5702-5711, database is CAplus and MEDLINE.
A nickel-catalyzed intramol. C-N coupling reaction via SO2 extrusion was presented. The use of a catalytic amount of BPh3 allowed the transformation to take place under much milder conditions (60°C) than previously reported C-N coupling reactions by CO or CO2 extrusion (160-180°C). In addition, this method displayed good functional group tolerance and versatility, as it can be applied to the synthesis of dialkyl aryl amines, alkyl diaryl amines and triaryl amines. The robustness of the desulfitative C-N coupling was demonstrated by three high-yielding gram-scale reactions.
