Experimental study demonstrates efficient aerobic dehydrazination in diverse arylhydrazines, highlighting a practical catalytic route to substituted aromatics.
An efficiently aerobic dehydrazination of arylhydrazines promoted by potassium tert ‐butoxide ( t BuOK) is detailed in this study. This method smoothly produces aromatics analogues from arylhydrazines using catalytic amount of t BuOK under practical conditions, exhibiting excellent functional group tolerance and a broad substrate scope. The application potential of this approach is further demonstrated through the preparation of deuterated, iodinated and brominated aromatics. Moreover, it shows that this aerobic base‐mediated dehydrazination could be utilized to prepare unsymmetrical aryl sulfides, selenides and tellurides with high efficiency.
