The tBuLi-promoted intermolecular direct nucleophilic addition of arenes to diazo compounds as the N-terminal electrophiles has been developed. This reaction proceeds in a completely regioselective manner and is an efficient method for the preparation of hydrazine derivatives in high to excellent yields. This transformation not only provides an efficient approach for aromatic C–N bond formation under transition-metal-free and oxidant-free conditions but also represents a strategy for the 3-amination of pyridines and the dearomatization of indoles.
