摘要

We have developed unprecedented methods for the direct transformation of primary alcohols to alkenes in the presence of hydrazine, and for the synthesis of mixed alkenes by the reaction of alcohols with hydrazones. The reactions are catalyzed by a manganese pincer complex and proceed in absence of added base or hydrogen acceptors, liberating dihydrogen, dinitrogen, and water as the only byproducts. The proposed mechanism, based on preparation of proposed intermediates and control experiments, suggests that the transformation occurs through metal-ligand cooperative N-H activation of a hydrazone intermediate.

Manganese-Catalyzed Chemoselective Coupling of Secondary Alcohols, Primary Alcohols and Methanol

Jun Tang, Jingxi He, Sheng-Yin Zhao, Weiping Liu

Summary: Here, we report a manganese-catalyzed three-component coupling reaction for the synthesis of beta,beta-methylated/alkylated secondary alcohols. Our method efficiently constructs assembled alcohols with high chemoselectivity in moderate to good yields using a series of 1-arylethanol, benzyl alcohol derivatives, and methanol. Mechanistic studies suggest that the reaction proceeds via methylation of a benzylated secondary alcohol intermediate to generate the final product.

Divergent Synthesis of Alcohols and Ketones via Cross-Coupling of Secondary Alcohols under Manganese Catalysis

Feixiang Sun, Jiamin Huang, Zhihong Wei, Conghui Tang, Weiping Liu

Summary: A homogeneous manganese-catalyzed cross-coupling reaction of secondary alcohols was developed for the synthesis of gamma-disubstituted alcohols and beta-disubstituted ketones. The protocol, using Mn-MACHO(Ph) as the catalyst, exhibited a wide substrate scope and good functional group tolerance, resulting in diverse valuable disubstituted alcohols and ketones in moderate to good yields. The selective formation of alcohol products was found to be influenced by reaction temperature, with alcohols favored over ketones at lower temperatures.

Cross-dehydrogenative N-N couplings

Alexis Tabey, Pooja Y. Vemuri, Frederic W. Patureau

Summary: The high electronegativity of nitrogen presents challenges for N-N bond forming cross-coupling reactions, especially in an intermolecular fashion. Dehydrogenative N-N coupling reactions are advantageous in terms of step and atom economy, but require careful design of an oxidizing system to avoid unwanted side reactions. Despite the importance of N-N bonds in organic chemistry, only a few intermolecular hetero N-N cross-dehydrogenative couplings exist, highlighting the need for further research in this area.

Catalytic Aerobic Oxidation of Hydrazines into 2-Tetrazenes

Anne Renault, Lionel Joucla, Emmanuel Lacote

Summary: In this study, a catalytic formation of 2-tetrazenes was reported, which involved the copper (ii) promoted oxidation of hydrazines in the presence of bipyridine ligands using air or dioxygen as the terminal oxidant. The method successfully produced symmetrical tetrazenes, which were previously prepared using toxic or stoichiometric oxidants. Additionally, the catalytic reaction could be used for the formation of cyclic tetrazenes and dissymmetric structures under certain conditions.

Manganese Catalyzed Hydrogenation of Azo (N=N) Bonds to Amines

Uttam Kumar Das, Sayan Kar, Yehoshoa Ben-David, Yael Diskin-Posner, David Milstein

Summary: The first example of homogeneously catalyzed hydrogenation of the N=N bond of azo compounds has been reported using a complex of an earth-abundant-metal. The hydrogenation reaction is catalyzed by a manganese pincer complex, proceeds under mild conditions, and yields amines, which makes this methodology a sustainable alternative route for the conversion of azo compounds. A plausible mechanism involving metal-ligand cooperation and hydrazine intermediacy is proposed based on mechanistic studies.
