The ceria-supported rhenium catalyst modified with palladium (ReOx-Pd/CeO2 (Re = 2 wt %, Pd/Re = 0.25)) is still the best catalyst for simultaneous hydrodeoxygenation. Higher Re loading amount decreased the activity. The simultaneous hydrodeoxygenation of cyclic vicinal diols occurs with high cis-stereoselectivity. ReOx-Pd/CeO2 catalysts were characterized by means of XRD, TEM, H2-TPR, XAFS, XPS, Raman, and DFT calculations. The Re species on ReOx-Pd/CeO2 (Re = 2 wt %, Pd/Re = 0.25) catalyst after reduction and after stoichiometric reaction of 1,2-hexanediol to 1-hexene were ReIV and ReVI, and the ReIV species were converted to ReVI through the stoichiometric reaction. The Re species on ReOx-Pd/CeO2 are proposed to be randomly located on the CeO2 surface, and probably only monomeric Re species have catalytic activity for simultaneous hydrodeoxygenation. This model can explain the higher activity of Re = 2 wt % catalyst than those of higher Re loading catalysts. The reaction is proposed to proceed by the tetra/hexavalent redox cycle of the Re center in the catalysis followed by hydrogenation.

Application of 453-20-3, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.453-20-3, Name is 3-Hydroxytetrahydrofuran, molecular formula is C4H8O2. In a Review，once mentioned of 453-20-3

Ethers are generally less reactive than other functionalized compounds such as alcohols. Therefore, cleavage of one of the C-O bonds in an ether group is not common in organic synthesis, except in the case of very reactive ethers such as benzyl ethers, tert-butyl ethers, and epoxides. The presence of two C-O bonds in each ether group causes another problem for the utilization of ether transformations in organic syntheses: The conversion of unsymmetrical ethers can produce two different sets of products. However, the recent focus on biomass conversion has renewed interest in ether conversions, because biomassderived materials often contain ether groups. An example of this is lignin,[1] which is a complex polyether of propylbenzene units. Furan derivatives are also important biomass-derived compounds.[2,3] Biomass resources generally contain large amounts of oxygen atoms and many functional groups. Removal of ether oxygen is one of the main reactions in biomass conversion, and ether hydrogenolysis (Scheme 1) achieves this end.

The original synthesis of glycopyrrolate (NVA237) was revised and shortened into an essentially one-pot process. Without isolating the intermediates, their purification became obsolete, thereby increasing the possibility of the carry over of impurities. For that reason, the actual, potential, and theoretical impurities of the starting materials cyclopentyl mandelic acid and 1-methyl-pyrrolidin-3-ol as well as byproducts which may occur during the synthesis were thoroughly investigated; furthermore, their transformation to possible impurities in the drug substance along the new synthetic route was performed to exclude them as actual impurities in the drug substance with certainty. The question is raised how detailed such investigation-which are fairly manageable for a simple product like glycopyrrolate-need to be.

Bimetallic Rh-ReOx (Re/Rh molar ratio 0.4?0.5) catalysts supported on TiO2 and ZrO2 were prepared by the successive impregnation of dried and calcined unreduced supported Rh catalysts. Their catalytic performances were evaluated in the hydrogenolysis of erythritol to butanetriols (BTO) and butanediols (BDO) in aqueous solution at 150?240 C under 30?120 bar H2. The activity depended on the nature of the support, and the highest selectivity to BTO and BDO at 80 % conversion was 37 and 29 %, respectively, in the presence of 3.7 wt %Rh-3.5 wt %ReOx/ZrO2 at 200 C under 120 bar. The characterization of the catalysts by CO chemisorption, TEM with energy-dispersive X-ray spectroscopy, thermogravimetric analysis with MS, and X-ray photoelectron spectroscopy suggests a different distribution and reducibility of Re species over the supported Rh nanoparticles, which depends on the support.
