Since its introduction to organic synthesis in 1977 by Kagan, 1, 2 samarium (II) iodide (SmI2,
Kagan's reagent) has gained the status of one of the most versatile single-electron transfer …

The transfer hydrogenation of azoarenes to hydrazoarenes using ethanol as a hydrogen
source by a bidentate Ru (II)-NC complex is developed. A weak base is crucial for this …

A catalyst-and metal-free hydrogenation of azobenzenes to hydrazobenzenes in the
presence of thioacetic acid was achieved under visible light irradiation. The transformation …

A nickel-catalyzed semihydrogenation of azoarenes to hydrazoarenes with NH3BH3 is
developed. The catalytic system exhibits good functional group tolerance and a high …

Minute amounts of supported Au nanoparticles on TiO2 (0.1 mol%) catalyze quantitatively at
room temperature the transfer hydrogenation of azoarenes to hydrazoarenes by ammonia …

The high atom-economical and eco-benign nature of hydrogenation reactions make them
much more superior to conventional reduction and transfer hydrogenation. Herein, a …

The combination of Sm (II)-based reductants with water provides reagent systems that
promote a range of reductions and bond-forming reactions that are endergonic based on …

Samarium (II) iodide–water–amine reagents have emerged as some of the most powerful
reagents (E°=− 2.8 V) for the reduction of unactivated carboxylic acid derivatives to primary …

Hydrazoarenes are important structural components extensively utilized across diverse
industries, such as dyes and pharmaceuticals; they are also vital in supramolecular …

A highly efficient and chemoselective approach for the divergent assembling of
unsymmetrical hydrazines through an unprecedented intermolecular desulfurdioxidative N …
