Rh(III)-catalyzed [4?+?1]-annulation of azobenzenes with α- carbonyl sulfoxonium ylides toward 3-acyl-(2H)-indazoles

A Rh(III)-catalyzed [4 + 1]-annulation of azobenzenes with α- carbonyl sulfoxonium ylides was developed to access 2H-indazoles in moderate to excellent yields with good functional group compatibilities. It proceeded with the sequential insertion of the Rh(III) carbene to the C?H bond and cyclization steps, where sulfoxonium ylides served as efficient and stable carbene precursor.

Oxidative dehydrogenation of hydrazines and diarylamines using a polyoxomolybdate-based iron catalyst

We report an efficient method for the oxidative dehydrogenation of hydrazines and diarylamines in aqueous ethanol using Anderson-type polyoxomolybdate-based iron(iii) as a catalyst and hydrogen peroxide as an oxidant. A series of azo compounds and tetraarylhydrazines were obtained in moderate to excellent yields. The reaction conditions and substrate scopes are complementary or superior to those of more established protocols. In addition, the catalyst shows good stability and reusability in water. The preliminary mechanistic studies suggest that a radical process is involved in the reaction.

One step synthesis of azo compounds from nitroaromatics and anilines

A general and efficient method for synthesis of both symmetric and asymmetric aromatic azo compounds in one single step has been developed. The nitro compounds were reduced and the substituted anilines were oxidized by each other without any metal in the

Transitional-Metal-Activated Organic Compounds, XXXV. - ortho-Alkylation of Aromatic Azo Compounds with Alkyllithium Reagents and Lithium Trimethylferrate(1-)

Whereas methyllithium reacts with 4-(dimethylamino)-, 4-amino-, and 4-methoxyazobenzene, respectively, by ortho-methylation of the electron-rich phenyl residue of the azo compound, (CH3)3FeLi ortho-methylates the less electron-rich phenyl group of 4-(dimethylamino)azobenzene.A mechanistic rationalization is given for both reaction modes.Key Words: Lithium, organo compounds / Iron, organo compounds / Azo compounds / ortho-Alkylation
