Synthesis of Hydrazines via Radical Generation and Addition of Azocarboxylic tert -Butyl Esters

A new chemistry of azo compounds that is a radical generation and addition in situ of azocarboxylic tert-butyl esters to synthesize hydrazines has been described. The protocol provides a novel strategy for the synthesis of various hydrazines. The advantag

Aerobic Oxidation of Alkyl 2-Phenylhydrazinecarboxylates Catalyzed by CuCl and DMAP

Recently, various fruitful organic reactions such as a catalytic Mitsunobu reaction were reported by virtue of alkyl 2-phenylazocarboxylates, however, the synthesis of alkyl 2-phenylazocarboxylates largely depended on the stoichiometric use of toxic oxidants. In this manuscript, an environment-friendly aerobic oxidative transformation of alkyl 2-phenylhydrazinecarboxylates to alkyl 2-phenylazocarboxylates is disclosed. The use of CuCl and DMAP system efficiently catalyzed the aerobic oxidation of alkyl 2-phenylhydrazinecarboxylates under mild conditions. The reaction rate of the present Cu-catalysis was much faster than that of the previously reported Fe-catalysis, and a variety of azo products were synthesized within 3 h. The present protocol was effective on larger scale. It was observed that the produced azo compound could undergo various reactions without isolation through one-pot sequential protocols.

Copper-Catalyzed Cascade Substitution/Cyclization of N-Isocyanates: A Synthesis of 1-Aminobenzimidazolones

A copper-catalyzed cascade reaction of in situ generated nitrogen-substituted isocyanates (N-isocyanates) and 2-iodoanilines has been developed. The cascade relies on the base-catalyzed substitution of masked N-isocyanates, followed by Cu(I)-catalyzed cou

Rhodium(III)-catalyzed cyclative capture approach to diverse 1-aminoindoline derivatives at room temperature

A RhIII-catalyzed C-H activation/cyclative capture approach, involving a nucleophilic addition of C(sp3)-Rh species to polarized double bonds is reported. This constitutes the first intermolecular catalytic method to directly access 1-aminoindolines with a broad substituent scope under mild conditions.

Investigation of the oxidation ability of protected hydrazine derivatives

In the present paper we have determined the oxidation potentials for several protected hydrazine derivatives using cyclic voltammetry. For comparison the chemical oxidation of these hydrazines was also studied.

Arylation of diversely substituted hydrazines by tri- and pentavalent organobismuth reagents

Various hydrazine derivatives were studied with respect to arylation by triarylbismuthane and triarylbismuth diacetate reagents with emphasis on scope and limitations. Among these reagents, a few contained bulky substituents in their aromatic rings. The a
