the growing demand for green and sustainable chemical processes, the catalytic reductivealkylation of amines with main-group catalysts of low toxicity and molecular hydrogen as the reductant would be an ideal method to functionalize amines. However, such a process remains challenging. Herein, a novel reductivealkylation system using H2 is presented, which proceeds via a tandem reaction that involves
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
