Efficient visible-light-driven selective conversion of glucose to high-value chemicals over Bi2WO6/Co-thioporphyrazine composite in aqueous media

Selective photocatalytic oxidation of glucose to high-value chemicals in aqueous media using atmospheric oxygen as oxidant and solar light as driving force is a greatly attractive topic. Herein, Bi2WO6/CoPz (cobalt tetra(2,3-bis(butylthio)maleonitrile) porphyrazine) composite was served as a visible-light photocatalyst towards selective oxidation of glucose to high-value arabinose and formic acid in aqueous media, which was performed under visible light (λ ≥ 420 nm) irradiation using atmospheric oxygen as oxidant. The reactive parameters for glucose oxidation, such as light intensity, CoPz content, glucose concentration and active species, were studied. The highest activity for Bi2WO6/CoPz composite was obtained when the CoPz content was 0.25 %. Under the optimum reaction conditions, 96.8 % of total selectivity towards arabinose and formic acid at 45.3 % of glucose conversion was obtained after reacting 3 h. The critical role of CoPz and the rationale behind the high photocatalytic performance for Bi2WO6/CoPz composite were further investigated using various techniques.

Synthesis of racemic ribose from D-glucose

Racemic ribose is a valuable starting material for investigations of the origins of biomolecular homochirality. It can be synthesized in seven steps starting from D-glucose.

THE FORMOIN REACTION

The formoin reaction, i.e., the autocondensation of formaldehyde in an aprotic solvent catalysed by the conjugate base of a thiazolium ion, has been studied in detail.Glucose, galactose, dihyroxyacetone dimer, xylose, and arabinose have been identified as products.The influence of catalysts, temperature, basicity, and reaction time is documented.N,N-Dimethylformamide is a more convenient solvent than ether, benzene, or diglyme.Ethyldi-isopropylamine affords better yields of carbohydrate material than triethylamine.At =60 deg, aldol condensations are reduced to a minimum.After 1-2 h of reaction (depending on the conditions), the yields begin to decrease and become zero after ca. 24 h.
