A novel palladium-catalyzed Heck coupling reaction of arylhydrazines with olefins is described, which affords various styrenes with high efficiency. This transformation proceeds through a C-NHNH2 bond activation under mild conditions.

A single-step synthesis of N-aryl-N′-tosyldiazenes from primary aromatic amines was developed. A wide range of aromatic amines provided the corresponding products in high yields by N–N bond formation with RhII–nitrene intermediates, which were generated in situ from dirhodium(II) complex catalysts and (tosylimino)-2,4,6-trimethylphenyliodinane, followed by oxidation. The synthesized N-aryl-N′-tosyldiazenes were successfully demonstrated to serve as potent and stable surrogates for diazonium salts in the two-step deaminative transformation of primary aromatic amines.

A convenient method for the synthesis of 2-arylazocarboxylates from 2-arylhydrazinecarboxylates by aerobic oxidation with iron phthalocyanine is described. The reaction is applicable to oxidative activation of 1-acyl-2-phenylhydrazines. Some preliminary experiments suggest Michaelis-Menten kinetics and participation of radical species in the reaction mechanism.
