The structural and chemical stabilities of immobilized polyoxometalate (POM)-containing catalysts are crucial factors for their industrial application. An alumina supported POM catalyst is prepared by using a facile condensation reaction between the trilacunary POM Na12[α-P2W15O56]?24 H2O (P2W15) and the hydroxy groups on the surface of γ-Al2O3spheres under acidic conditions. The heterogeneous catalyst P2W15?Al2O3is characterized by a wide variety of techniques and shows excellent stability and highly efficient reactivity and selectivity for the oxygenation of thioethers to sulfoxides, which are a very useful intermediate in organic synthesis and the industrial preparation of drugs. Furthermore, P2W15?Al2O3can be recycled and reused at least ten times without any observable loss of its catalytic efficiency, mainly due to the covalent immobilization and high dispersion of P2W15on the γ-Al2O3surface.

Dannenberg,Fritze,Krauskopf,Bolm
, p. 1086 - 1090 (2017)
A transition metal-free synthesis of N-cyanosulfoximines from sulfoxides using N-chlorosuccinimide (NCS) as oxidising agent and cyanamide as nucleophilic amine source is reported. The products are obtained in moderate to excellent yields. The protocol enables an easy access to N-cyanosulfoximines from readily available starting materials under inversion of configuration at a preexisting stereogenic center.

Four inorganic-organic hybrid octa-Cu cluster sandwiched polyoxotungstates (POTs), [Cu8(H2O)2(en)4(B-α-H2SiW9O34)2] (1), [Cu8(H2O)2(en)4(B-α-H2GeW9O34)2] (2), K2[Cu8(en)4(B-α-HSiW9O34)2]·6H2O (3), and K2[Cu8(en)4(B-α-HGeW9O34)2]·2H2O (4) (en = ethylenediamine), were hydrothermally made and characterized by single-crystal X-ray diffraction, infrared spectra, powder X-ray diffraction, and thermogravimetric analysis, respectively. Structure analysis reveals that the polyoxoanion of 1/2 is a discrete dimer built by two trivalent Keggin [B-α-XW9O34]10- (X = Si/Ge) fragments and one octa-Cu cluster, whereas 3 and 4 display a two-dimensional network built by octa-Cu-sandwiched POT units via substitution of coordinated water on polyanions of 1 and 2 and further expand into a three-dimensional framework via K cation bridges. Ultraviolet-visible diffuse reflectance spectra reveal that 1-4 are potential semiconductor materials. Moreover, its visible light-driven catalytic H2 evolution activity, electrochemical properties, catalysis for oxygenation reactions of thioethers, and magnetic behaviors have been investigated in detail.

, (2022/03/08)
The first example of heterometallic Ag/Ti bimetallic-based coordination polymer was synthesized using salicylic acid as the ligand. The uniform Ag/Ti?O rod array has efficient electrocatalytic CO2 reduction activity with a Faradaic efficiency (FE) of 90.3 % at ?0.88 V (vs RHE) and a maximum TOF of 658 h?1 at ?1.08 V. The chemical catalytic property of the Ag/Ti?O rod was also studied, and the results showed that the Ag/Ti?O rod has good catalytic performance for selective oxidation of sulfide to sulfoxide.

A facile and efficient visible-light-mediated method for directly converting sulfides into sulfoxides under clean conditions without using any photocatalysts is reported. This method exhibited favourable compatibility with functional groups and afforded a series of sulfoxides with high selectivity and yields. Moreover, in order to shed more light on such a transformation, detailed mechanism studies were carried out both experimentally and theoretically. The readily accessible, low-cost and eco-friendly nature of the developed method will endow it with attractive applications in chemical synthesis.
