The complex [CoII(qpy)(OH2)2]2+ (qpy = 2,2′:6′,2′′:6′′,2′′′-quaterpyridine) is an efficient visible light-driven catalyst for both water oxidation and reduction. It catalyses photochemical oxygen evolution from at pH 8.0 with [RuII(bpy)3]2+/S2O82− (λ 457 nm, max TON 335, bpy 2,2′-bipyridine). also hydrogen generation [IrIII(dF(CF3)ppy)2(dtbbpy)]+/TEOA (dF(CF3)ppy anion of 2-(2,4-difluorophenyl)-5-trifluoromethylpyridine, dtbbpy 4,4′-di-tert-butyl-2,2′-bipyridine, TEOA triethanolamine) in...
The first asymmetric transfer hydrogenation of cyclic imines and iminiums in water was successfully performed high yields enantioselectivities with sodium formate as the hydrogen source CTAB an additive catalyzed by a water-soluble recyclable ruthenium(II) complex ligand (R,R)-2.
A novel water-soluble rhodium(III)catalyst prepared from o,o′-aminated N-tosyl-1,2-diphenylethylenediamine(S,S)-3 and [Cp*RhCl2]2, which was efficient for the asymmetric transfer hydrogenation of ketones imines in neat water with high reactivity excellent enantioselectivity, has been developed.
A series of spirooxindole tetrahydrofuran derivatives were obtained in moderate to good yields <italic>via</italic> base-mediated cascade [3+2] double Michael reactions under mild conditions. Their antifungal effects on selected five target phytopathogenic fungi investigated, and their structure activity relationships also discussed.
Water-soluble ligands (R,R)-2 were successfully prepared, in which the bis-meta-sulphonated ligand was definitely detected as major product. The corresponding transition-metal complexes containing displayed excellent catalytic performance asymmetric transfer hydrogenation (ATH) of aromatic ketones. Especially, ketones with a bromine group α position could be smoothly reduced to expected alcohol, keeping intact enantioselectivities (up 96% ee). catalyst reused at least 21 times without...
Gold nanoparticles stabilized by sulfhydryl functionalized pillar[5]arenes were successfully prepared. When they complex with anthracene derivatives on their surfaces, can reversibly aggregate and disassemble based photocycloaddition of anthracene.
A metal-free method for efficient and chemoselective reduction of α-ketoamides using DMF/NaOH/H<sub>2</sub>O system has been developed.
The formation of a pH-responsive fluorescent [5]pseudorotaxane by self-assembly cationic water-soluble pillar[5]arenes and tetraphenylethene derivative was reported.
Various nanomorphologies were obtained by simply changing the fabrication conditions, such as pH of system, different solvent, or concentration, bola-amphiphilic pillar[5]arene Bola-AP5. Importantly, hybrid microtubules a microreactor successfully prepared directly reducing AuCl4(-) on surface Bola-AP5-based tubular structures in water.
A catalyst‐ and additive‐free chemoselective transfer hydrogenation of α‐keto amides to α‐hydroxy is easily achieved by using sodium formate as a hydrogen source. The utility this method demonstrated gram‐scale synthesis transformation the resultant into polysubstituted acetamides 2‐arylindole derivatives. Control experiments suggest that NH group crucial for reduction through formation bonds.
A practical and operationally simple hydrodehalogenation of halogenated carboxylic acid derivatives using a DMSO/HCOONa·2H2O system is developed. This protocol avoids the involvement light irradiation, electrochemical apparatus, transition metals, radical initiators, strong bases, other additional additives. Control experiments suggest that HCOONa might function as hydride donor in reduction process via nucleophilic substitution or addition to achieve hydrodehalogenation.
