Controlled reactions of 2,3-allenoates with a 1,3-diketone catalyst effect

Two types of reactions of 2,3-allenoates with 1,3-diketones under different reaction conditions are described: under palladium catalysis, the relatively electron-rich C=C bonds are attacked to afford ethyl (2E)-4-acyl-2-alkyl-4-aryl- 6-oxohept-2-enoates exclusively with dicyclohexyl(2,4,6-trimethoxyphenyl) phosphane as the ligand; under Cu(OAc)2 catalysis, 4-[R-C(=O)-]-(LB-Phos) 3,5-dialkyl-3-(2-oxo-2-arylethyl)furan-2(3H)-one products are formed unexpectedly through intramolecular reaction at the electron-deficient C=C bond.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.COA of Formula: C5H8O2, you can also check out more blogs about1679-47-6

Selective dehydration of glucose to 5-hydroxymethylfurfural on acidic mesoporous tantalum phosphate

Mesoporous tantalum phosphate was prepared from tantalum tartrate and ammonium phosphate monobasic in the presence of an ionic surfactant at room temperature, and subsequent calcined at 550C. This solid exhibits a high specific surface area (256m2g-1) and strong acidity (1.48mmolNH3g-1), and it has been successfully used as solid acid catalyst in the dehydration of glucose to 5-hydroxymethylfurfural (HMF) in a biphasic water/methyl isobutyl ketone medium. By using a glucose:catalyst weight ratio of 3:1, a glucose conversion of 56.3% and a HMF yield of 32.8% were achieved at 170C, and after only 1h of reaction time. The reaction is very selective towards HMF, which is the unique product detected and moreover it is preserved from ulterior hydration to levulinic acid. Fructose was never found as by-product in the reaction. The catalyst is very stable under these experimental conditions, since no leaching of phosphorus or tantalum species to the liquid phase was found. The catalytic performance of this acid solid is well maintained after three catalytic cycles. The high catalytic activity of this mesoporous solid in the dehydration of glucose could be associated to its high acidity and the presence of both Bro?nsted and Lewis acid sites, which are maintained in water.

Evolution of quality parameters during red wine dealcoholization by osmotic distillation

Osmotic distillation technique was used for the total dealcoholization of a red wine (Aglianico grape variety) up to 0.19 vol.%. The dealcoholization process was performed in subsequent cycles which gave rise wine samples at different alcoholic degrees. The effect of processing on the main chemical and physical properties of Aglianico wine was evaluated. Among wine samples, no significant differences (p < 0.05) of oenological parameters such as pH, total acidity were found. Similarly, the total phenolic, flavonoids and tartaric esters content and the composition of organic acids did not show significant differences (p < 0.05) during the process. On the contrary, colour intensity and tonality of wine samples changed significantly when the alcohol reduction was over the 6.5 vol.%. Finally, the total dealcoholized wine showed properties similar to Aglianico wine except for the volatile compounds, which decreased over 98%. Hence, flavour enrichment may be required to produce a pleasurable and delicious non alcoholic beverage from wine.

A “bottom-up” approach to process development: Application of physicochemical properties of reaction products toward the development of direct-drop processes

The “bottom-up” approach to development of direct-drop processes is a powerful, yet simple, strategy that every process chemist should consider for the development of efficient, cost-effective, and environmentally friendly processes. This approach is aided by a “parallel crystallization” technique, which allows for rapid identification of multiple solvent systems for the crystallization of the desired product using a minimal amount of material and solvent. This “bottom-up” approach is illustrated by several examples where the desired product is crystallized directly from the reaction mixture.

Monitoring surface processes during heterogeneous asymmetric hydrogenation of ketones on a chirally modified platinum catalyst by operando spectroscopy

Surface processes occurring at the catalytic chiral surface of a cinchona-modified Pt catalyst during the asymmetric hydrogenation of activated ketones have been monitored for the first time using operando ATR-IR spectroscopy. Fundamental information about this catalytic system could be gained, including the chiral modification process of the catalyst, the surface interaction of reactant ketone with preadsorbed chiral modifier, the role of hydrogen as well as the influence of the product enantiomers in the catalytic cycle. The formation of a diastereomeric transient surface complex between ketone and chiral modifier was found to be related to the ketone consumption. Among the studied activated ketones, a correlation between stereoselection and the strength of the intermolecular hydrogen bond was identified. Dissociated hydrogen from the catalytic surface is found to play a crucial role in the formation of the diastereomeric surface complex.
