Electrochemical fluorination of several esters derived from oxolane-2-yl-carboxylic acid, oxolane-2-yl-methanol and oxane-2-yl-methanol

Electrochemical fluorination (ECF) of the ester derivatives of oxolane-2-yl-carboxylic acid (1), oxolane-2-yl-methanol (2) and oxane-2-yl-methanol (3) were investigated. Perfluoro(oxolane-2-yl- carbonylfluoride) (4) was obtained from derivatives of 1 and 2, and perfluoro(oxane-2-yl-carbonylfluoride) (5) was obtained from derivatives of 3 as the desired compounds, respectively. From the ECF of acetates of 2 and 3, perfluorospiroethers having a dioxolane ring were also obtained as the cyclization product in low yield together with the desired perfluoroacid fluoride (4 and 5). The structure of these perfluorospiroethers was confirmed by analyzing the chlorinated products, which were obtained by the reaction with AlCl3.

Odor impact of volatiles emitted from marijuana, cocaine, heroin and their surrogate scents

Volatile compounds emitted into headspace from illicit street drugs have been identified, but until now odor impact of these compounds have not been reported. Data in support of identification of these compounds and their odor impact to human nose are presented. In addition, data is reported on odor detection thresholds for canines highlighting differences with human ODTs and needs to address gaps in knowledge. New data presented here include: (1) compound identification, (2) gas chromatography (GC) column retention times, (3) mass spectral data, (4) odor descriptors from 2 databases, (5) human odor detection thresholds from 2 databases, (6) calculated odor activity values, and (7) subsequent ranking of compounds by concentration and ranking of compounds by odor impact (reported as calculated odor activity values). For further interpretation and discussion, see Rice and Koziel [1] and Rice [2].

Highly selective one-pot conversion of THP and MOM ethers to acetates by indium triiodide-catalysed deprotection and subsequent transesterification by ethyl acetate

The chemoselective one-pot conversion of tetrahydropyranyl (THP) and methoxymethyl (MOM) ethers of primary alcohols to the corresponding acetates was presented. It was done using indium triiodide-catalysed deprotection and subsequent acetylation by ethyl acetate through a transesterification process. The advantages offered by the method included operational simplicity, ‘green’ methodology involving no toxic or hazardous chemicals and high yield.

Regioselective cleavage of tetrahydrofurans bearing proximate functional groups with acid iodides

Tetrahydrofurans functionalized at the C2 or C3 position (alcohols, esters, amine, ether, acetal) are cleaved with RCOCl/NaI (R = Me, tBu) in acetonitrile to give regioselectively trifunctionalized derivatives. In all cases the cleavage occurs mainly or exclusively at the C-O bond the most remote from the functional group.

Bi(III) halides as efficient catalysts for the O-acylative cleavage of tetrahydrofurans: An expeditious entry to tetralins

The mild (DCM/20C), quantitative, regioselective, O-acylative cleavage of tetrahydrofurans using organic acid halides with catalytic Bi(III) halides is reported. X-ray crystallography is used to rationalise the failure of the reaction in the case of certain crowded acid chlorides, and a useful aspect of chemoselectivity is revealed. The synthetic potential of this reaction is illustrated with a highly efficient O-acylative cleavage/intramolecular alkylation approach to tetralins.

Enhancement in hydrophobicity of low rank coal by surfactants – A critical overview

The flotation of fine (- 0.5 mm) low rank or oxidized coal is difficult to achieve with the common coal flotation collectors like kerosene, fuel oil or diesel oil (oily collector). The presence of small amounts of oxygen is enough to cause oxidation. The oxidation of coals starts with the physical adsorption of oxygen on the surface to form an oxycomplex followed by chemical adsorption of oxygen to form polar phenolic-OH, carbonyls, phenols and peroxide type oxygenated moieties by the rupture of cyclic rings. The addition of promoter, surfactant or oxygenated functional groups to the collector molecule markedly enhances the flotation of lower rank and oxidized coals due to the hydrogen bonding with the polar part of the coal surface and the reagent. The performance of these reagents is compared with that of oily collectors, namely kerosene, dodecane, nonylbenzene and polar part of the surfactant having an oxygen atom. The mode of addition of non-ionic surfactant with oily collector also has a major role in the flotation response. The addition of non-ionic surfactant after the oily collector has shown a positive effect on yield and grade.

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.SDS of cas: 637-64-9, you can also check out more blogs about637-64-9

Oxidative acetoxylactonisation of alkenoic acids using H2O2 in acetic acid catalysed by KI

In the presence of a catalytic amount of KI in combination with H2O2, a convenient catalytic procedure has been developed for the direct preparation of acetoxylactones from alkenoic acids in acetic acid at room temperature which provides the corresponding cyclic products in good yields. This novel methodology mediated by an in situ generated hypervalent iodine intermediate extends the catalytic application of KI in organic synthesis.
