Abstract:

Utilizing the sulfur-containing gases of garlic as probes, we investigated the gut versus mouth origin of odoriferous breath gases. Five individuals ingested 6 g of garlic, and sulfur gases in mouth, alveolar air, and urine samples were measured. The mouth normally contained low concentrations of hydrogen sulfide, methanethiol, and dimethyl sulfide. Immediately after garlic ingestion, transient high concentrations of methanethiol and allyl mercaptan and lesser concentrations of allyl methyl sulfide (AMS), allyl methyl disulfide, and allyl disulfide were observed. With the exception of AMS, all

Abstract:

Selected sulfur compounds found in cabbage and its fermentation product, sauerkraut, were tested for minimum inhibitory concentration (MIC) against growth of 15 species of bacteria and 4 species of yeasts. S-Methyl-l-cysteine sulfoxide, sinigrin, and dimethyl sulfide at 500 ppm were not inhibitory to any of the bacteria and yeasts tested. Dimethyl disulfide at 500 ppm retarded some, but did not prevent growth of any of the test microorganisms. Dimethyl trisulfide had an MIC to bacteria of 200 ppm and to yeast of 20 ppm. Methyl methanethiosulfinate had an MIC between 50 and 200 ppm for all bact

Abstract:

The kinetic behaviours of oxidation of dialkyl, alkyl aryl and diphenyl sulfides are quite different with pyridinium dichromate in acetonitrile medium; studies indicate the involvement of a sulfur cation free radical intermediate in diphenyl sulfide oxidation; electron releasing and withdrawing groups retard the reactivity of aryl methyl sulfides; the observed non-linear concave downwards type Hammett plot is well explained by assuming shifts in the rate-limiting step within the same overall reaction pathway.

Abstract:

Although 2-hydroxybenzaldehyde acylhydrazones, such as salicylaldehyde acylhydrazones, are intriguing bioactive molecules, few of their N-alkylated derivatives are known, and only methyl analogues have been reported previously. We achieved selective N-alkylation of 2-hydroxybenzaldehyde acylhydrazones, as their Fe(III) complexes, by using combinations of alkylating agents (for example, an alkyl bromide and a dialkyl sulfate). Fifteen substrates were examined, and 45 new 2-hydroxybenzaldehyde acyl(alkyl)hydrazones were synthesized in moderate to good yields. In all cases, the target products we

Abstract:

The concentration dependence of the conductance in aqueous solution of a series of benzyltrialkylammonium chlorides, nitrates and sulfates was measured. The n-alkyl substituents in this series were methyl, ethyl, propyl , butyl and pentyl. The conductances of the chlorides, nitrates and sulfates fit satisfactorily the electrostatic ion pairing models relevant to 1 : 1 and 1 : 2 electrolytes. The extent of ion pairing is small in all the solutions studied but consistently larger for nitrates and sulfates compared with chlorides. The dependence of the association constants on the alkyl substitut

Abstract:

The 1H nmr spectral parameters for 2-alkylthio derivatives benzaldehyde (alkyl = CH3, CH2CH3, CH(CH3)2, C(CH3)3) are used to show that the O-syn conformation of the aldehyde group decreases from 40% for the methyl to zero for the tert-butyl compound in CC14 solution at about 300 K. It appears that the alkylthio groups twist out of the benzene plane to the same extent as in the alkyl phenyl sulfides and that it is the concomitant approaches of the 3p lone-pairs on sulfur into the ring plane which, by repulsive interactions with the C=O bond, determine the conformations of the aldehyde group.

Quaternary salts were prepared by reaction of 4-amino-1,2,4-triazole and 4-amino-3,5-dialkyl- 1,2,4-triazoles (alkyl = Me, Et) with dimethyl and diethyl sulfate at ambient temperature. Subsequent ion metathesis gave hexafluorophosphates and bis(trifluoromethylsulfonyl)imides as crystalline derivatives or ionic liquids.Methylation at 100 ◦C gave the 4-(dimethylamino)-1-methyl-1,2,4- triazolium salt, a precursor for a new carbene ligand which was incorporated into Ag and Rh complexes. The synthesis of 5-bromo-4-(dimethylamino)-1-methyl-1,2,4-triazolium hexafluorophosphate is also reported. Cryst

Abstract:

Odour compounds in extracts of bleached kraft pulp mill effluent (BKME) have been characterized by olfactory gas chromatography (OGC) and gas chromatography-mass spectrometry. A variety of sulfury odours was detected by OGC in addition to woody and pulp mill-like odours. Three sulfur compounds were identified by comparison of retention times and partial mass spectra with authentic standards: dimethyl disulfide, 3-methylthiophene and thioanisole (methyl phenyl sulfide). Typical concentrations in BKME were 1, 0.05, and 0.5 μg/l, respectively. Their odour intensity is relatively low and they were

Abstract:

AbstractA hydrogen peroxide (H2O2)-mediated quinoxaline-2(1H)-ones hydrocarbylation reaction has been reported. The reaction is achieved through the difunctionalization of styrene. In this transformation, methyl radical resulting from dimethyl sulfoxide firstly attacks styrenes to provide alkyl radicals which then undergo alkylation at the C3 position of quinoxalin-2(1H)-one. A green, convenient, and simple protocol for the synthesis of 3-alkylquinoxalin-2(1H)-ones was provided.

Abstract:

Alkylation reactions of 2-phenylquinazoline-4-thion with methylation agents “soft” (methyl iodide) and “hard” (dimethyl sulfate, methyltozylate) were studied. It was found that the reaction proceeds with the formation of alkyl products at the N3 - and S4 - reaction centers, depending on the methylation agent, solvent and temperature. This indicated the ambivalent nature of the 2-phenylquinazoline-4-tion anion. Prolongation of the reaction time leaded to the formation of a second isomeric product (VII). A slight increase in phenyl N3-product (VII) yield was noted when dimethyl sulfate and methy
