Anomeric pairs of 3-(2-aminoethylthio)propyl D-galactopyranoside D-glucopyranoside and 2-acetamido-2-deoxy-D-glucopyranoside were prepared by addition of H2N(CH2)2SH to the corresponding anomeric allyl glycosides. The allyl α-glycosides were prepared by refluxing the sugars with allyl alc. in the presence of an acid catalyst; the allyl β-glycosides were prepared by the reaction of acetylated glycosyl bromides with allyl alc. in the presence of Hg(CN)2 followed by O-deacetylation. The rate of thiol addition to the allylic group was different for each glycoside.

Similarly, α-D-galactosidase catalyzed the formation of allyl α-D-galactopyranoside from raffinose and allyl alc. The galactosides were used as acceptors for the preparation of several galactopyranosylgalactopyranoside disaccharides.

Farsang, Evelin published the artcileAnalysis of non-ionic surfactant triton X-100 using hydrophilic interaction liquid chromatography and mass spectrometry, Related Products of alcohols-buliding-blocks, the main research area is Triton X 100 hydrophilic interaction liquid chromatog mass spectrometry; gradient optimization; hydrophilic interaction liquid chromatography; non-ionic surfactant; octylphenol–polyethoxylate.

It is well known that surfactants increase the solubility of hydrophobic organic compounds and cause adverse environmental effects. The removal of these compounds from the contaminated soil or ground-water is particularly difficult due to their water soluble feature. In this work, an ultra-high performance hydrophilic interaction liquid chromatog. method was developed for the separation of oligomers of Triton X-100 octylphenol-polyethoxylate non-ionic surfactant. Liquid chromatog.-mass spectrometry (LC-MS) was used to identify the Triton X-100 compounds There was a 44 mass unit difference between two adjacent peaks that is the molar mass of one ethylene oxide group (-CH2CH2O-). A quadratic retention model was applied for the estimation of retention of the examined non-ionic surfactant and the optimization of gradient elution conditions. The optimized method was suitable for the baseline separation of 28 Triton X-100 oligomers in five minutes.

Yang, Ji published the artcileDirect synthesis of adipic acid esters via palladium-catalyzed carbonylation of 1,3-dienes, Recommanded Product: 3-Pentanol, the main research area is palladium pyridyl bidentate phosphine ligand catalyzed carbonylation diene alc; adipic acid ester green preparation carbonylation diene alc.

The direct carbonylation of 1,3-butadiene offers the potential for a more cost-efficient and environmentally benign route to industrially important adipic acid derivatives However, owing to the complex reaction network of regioisomeric carbonylation and isomerization pathways, a selective practical catalyst for this process has thus far proven elusive. Here, we report the design of a pyridyl-substituted bidentate phosphine ligand (HeMaRaphos) that, upon coordination to palladium, catalyzes adipate diester formation from 1,3-butadiene, carbon monoxide, and butanol with 97% selectivity and 100% atom-economy under industrially viable and scalable conditions (turnover number > 60,000). This catalyst system also affords access to a variety of other di- and triesters from 1,2- and 1,3-dienes.

Wang, Azhong published the artcilePalladium-Catalyzed Direct Oxidation of Alkenes with Molecular Oxygen: General and Practical Methods for the Preparation of 1,2-Diols, Aldehydes, and Ketones, Related Products of alcohols-buliding-blocks, the main research area is terminal disubstituted olefin oxygen base palladium dihydroxylation; diol preparation; oxygen terminal disubstituted olefin PTSA palladium oxidative cleavage; aldehyde Ketone preparation green chem reaction mechanism; dihydroxylation oxidative cleavage catalyst palladium.

Novel and environmentally benign methods for palladium-catalyzed dihydroxylation and oxidative cleavage of olefins with oxygen as sole oxidant are presented. The cleavage reactions were performed with acid as additive in aqueous solution, whereas 1,2-diols were formed in the presence of base. A broad substrate scope has been demonstrated allowing monosubstituted aromatic and aliphatic terminal alkenes, 1,2-disubstituted, and 1,1-disubstituted olefins. The cleavage reactions of dioxo-PdII complexes implicate 1,2-diol might act as a key intermediate of olefin cleavage.

Wang, Man published the artcileMerging N-Hydroxyphthalimide into Metal-Organic Frameworks for Highly Efficient and Environmentally Benign Aerobic Oxidation, Safety of 3-Pentanol, the main research area is hydroxyphthalimide metal organic framework green oxidation catalyst; N-hydroxyphthalimide; aerobic oxidation; heterogeneous catalysis; metal-organic frameworks; nitroxyl radicals.

Two highly efficient metal-organic framework catalysts TJU-68-NHPI and TJU-68-NDHPI have been successfully synthesized through solvothermal reactions of which the frameworks are merged with N-hydroxyphthalimide (NHPI) units, resulting in the decoration of pore surfaces with highly active nitroxyl catalytic sites. When t-Bu nitrite (TBN) is used as co-catalyst, the as-synthesized MOFs are demonstrated to be highly efficient and recyclable catalysts for a novel three-phase heterogeneous oxidation of activated C-H bond of primary and secondary alcs., and benzyl compounds under mild conditions. Based on the high efficiency and selectivity, an environmentally benign system with good sustainability, mild conditions, simple work-up procedure has been established for practical oxidation of a wide range of substrates.

Moore, Peter W. published the artcileHydrogen-Bonding Interactions in the Ley-Griffith Oxidation: Practical Considerations for the Synthetic Chemist, HPLC of Formula: 111-87-5, the main research area is aldehyde preparation hydrogen bonding Ley Griffith oxidation primary alc.

The Ley-Griffith oxidation, which is catalyzed by tetra-n-propylammonium perruthenate (TPAP, nPr4N[RuO4]), is a popular method for not only controlled oxidation of primary alcs. to aldehydes, but also a host of other synthetically useful transformations. While the fundamental reaction mechanism has recently been elucidated, several key hydrogen-bonding interactions between the reagents were implicated but not investigated. Herein the prevalence of H-bonding between the co-oxidant N-methylmorpholine N-oxide (NMO), the alc. substrate, water and the perruthenate catalyst is established. These observations help to rationalize the importance of drying the reagents and lead to several practical suggestions.

Lagerspets, Emi published the artcileSchiff base Cu(I) catalyst for aerobic oxidation of primary alcohols, Name: 3-(Methylthio)propan-1-ol, the main research area is copper Schiff base complex catalyst preparation; aldehyde preparation; alc aerobic oxidation copper Schiff base complex catalyst.

New copper(I)-Schiff base complexes were reported for the selective aerobic oxidation of primary alcs. to aldehydes RCHO [R = (CH2)6, Ph, (CH2)2Ph, etc.] under ambient conditions. Particularly, the copper(I) complex bearing N-(4-fluorophenyl)-1-(furan-2-yl)methanimine showed high activity in the series and gave near- quant. yields in the oxidations of benzyl alc. (99% yield in 1 h) and 1-octanol (96% yield in 24 h). Based on the X-ray structure determination, the complex had a square pyramidal coordination accomplished by two N-(4-fluorophenyl)-1-(furan-2-yl)methanimine ligands and bromide as a counter anion. The oxidation reactions were monitored with UV-vis and in situ ATR-IR spectroscopy to study the changes in the catalytic structure and to elucidate the catalytic properties and the mechanistic details. Accordingly, detachment of one of the N-(4-fluorophenyl)-1-(furan-2-yl)methanimine ligands from the complexes was related to the oxidation activity.
