Azoxyarenes are among important scaffolds in organic molecules. Direct oxidativecoupling of primary anilines provides a concise fashion to construct them. However, whether these scaffolds can be prepared from secondary N-alkylanilines is not well explored. Here, we present a catalytic selective oxidativecoupling of secondary N-alkylaniline to afford azoxyarene with tungsten catalyst under mild conditions

preparation of a new air-stablenickelphosphite based catalyst for unique C–N bond forming processes. Specifically, (BINAP)Ni[P(OPh)3]2, is presented as an effective catalyst for a range of amination reactions between aryl halides and primaryalkylamines. The results are supported by relevant kinetic studies, DFT calculations and a catalytic cycle indicating possible reaction intermediates.
