A nickel-catalyzed intramolecular C - N coupling reaction via SO2 extrusion is presented. The use of a catalytic amount of BPh3 allows 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 displays 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 is demonstrated by three high-yielding gram-scale reactions.

Palladium-catalyzed alkynylation of arene C-H bonds with (triisopropylsilyl)acetylene was developed for the first time under oxidative conditions in the present study. Among various type of directing groups examined, the N-phenyl-2-aminopyridine skeleton was shown to be most effective and selective for the Pd-catalyzed direct alkynylation reaction, and the desired alkynylated products were obtained in moderate to good yields.
