The KOt-Bu promoted homocoupling and decomposition of N′-aryl acylhydrazines has been achieved. The method allows for a novel and efficient synthesis of unsymmetric N′,N′-diaryl acylhydrazines under mild reaction conditions. The reaction probably proceeds via the generation of N′-centered acylhydrazine radicals and the subsequent homolytic aromatic substitution.
