Aromatic carbonyl compounds in combination with B(C(6)F(5))(3) are able to activate H(2) heterolytically. The reactivity of the carbonyl-B(C(6)F(5))(3) adduct is initiated by its thermal dissociation into components. After H(2) addition, aromatic carbonyl compounds convert into aryl-substituted methanes or alcohols.

Recent improvements in the detection of alkylated aromatic compounds from gasoline accelerants in arson debris use expensive GC-MS-MS instrumentation that is not available to most crime laboratories. This research project uses solid-phase microextraction (SPME), an inexpensive pre-concentration method, to achieve high sensitivities in the analysis of alkylated aromatic compounds.

CF3-containing chiral imines readily react with α,α-difluoroenolates affording a novel type of β-keto-amino compounds featuring the R-CO-CF2-CH(NH2)-CF3 moiety. The reactions feature exceptional generality allowing preparation of various aromatic, hetero-aromatic and aliphatic derivatives in high yields and diastereoselectivity. The products are configurationally stable and can be transformed t...

Two general classes of compounds interfere with the synthesis of the hormone thyroxine in the thyroid gland. These are the thiocarbamides and what will be referred to here as the “aromatic” antithyroid compounds. The present state of knowledge on the mechanism and locus of action of these substances has been reviewed recently (l-3). There appears to be general agreement that the thiocarbamides ...

Increasing insight into the biosynthesis of aromatic substances has been obtained during the past few years primarily through the study of mutant strains of microorganisms,1 and by the use of isotopic carbon.2 Shikimic acid, reported to be involved in the biosynthesis of the aromatic amino acids and of p-aminobenzoic acid by Neurospora3 and Escherichia coli, has been shown to be derived in E. c...

Broadly applicable palladium-catalyzed heteroarene benzylation reactions are described with a focus on the most challenging heterocyclic classes under traditional benzylation techniques such as sulfur-containing heterocycles and those bearing functional groups that would be incompatible with reactions requiring Lewis acids and/or strong bases.

The aim of this study was to determine volatile compounds in dry dog foods and their possible influence on sensory aromatic profile. Grain-free dry dog foods were compared to dry dog foods manufactured with grain, but also with different protein sources for their aromatic volatiles. Solid-phase microextraction/gas chromatography/mass spectrometry was used to determine the aromatic compounds pre...

We evaluated 117 carbocyclic compounds for their bird repellent effects in no-choice (one-bottle) drinking tests and summarized the results in this paper. Compounds derivative of aromatic heterocycles, acetophenones and carbocyclic compounds containing sulfur are often strong repellents. Anthranilates, aromatic alcohols, aromatic aldehydes, and carbocyclic compounds containing nitrogen are mode...

Palladium nanoparticles (NPs) stabilized by ImS3-14, a zwitterionic surfactant structurally related to ionic liquids, are revealed here to be good catalysts for the reduction of a large number of substituted aromatic nitro compounds. Our mass spectrometry results are consistent with the formation of amino products in a direct route, where the aromatic nitro compounds are initially reduced to ni...
