Abstract:

A very sensitive mass-spectrometry method has been developed for the analysis of aromatic amines in tobacco smoke and in indoor air. Cigarettes were smoked with a smoking machine; the anwies from the smoke were trapped in a 5% HCl water solution containing internal standards and detected by gas chromatography/mass spectrometry in the selected-ion-monitoring (SIM) mode. The amines measured were the following: aniline. 2-toluidine, 3-toluidine, 4-toluidine, 2-ethylaniline, 3-ethylaniline, 4-ethylaniline, 2,3-dimethylaniline, 2,4-dimethylaniline, 2,5-dimethylaniline, 2,6-dimethylaniline, 1-naphth

Abstract:

AbstractRecent analyses conducted by German official food control reported detection of the aromatic amides N-(2,4-dimethylphenyl)acetamide (NDPA), N-acetoacetyl-m-xylidine (NAAX) and 3-hydroxy-2-naphthanilide (Naphthol AS) in cold water extracts from certain food contact materials made from paper or cardboard, including paper straws, paper napkins, and cupcake liners. Because aromatic amides may be cleaved to potentially genotoxic primary amines upon oral intake, these findings raise concern that transfer of NDPA, NAAX and Naphthol AS from food contact materials into food may present a risk t

Abstract:

There exists a diversity of pathways in mammalian cells serving to activate primary aromatic amines. 1 N-Oxidative mixed-function turnover usually involves participation of the cytochrome P450 superfamily, while catalysis by the flavin-containing monooxy genases is restricted to a few amines capable of forming imine tautomers. Surprisingly, haemoglobin metabo lizes cytotoxic and carcinogenic arylamines via a monooxygenase-like mechanism, but peroxygenase activity is also operative. 2 In extrahepatic tissues that exhibit only a low level of monooxygenases, peroxidative transformations, as are b

For aromatic amines, selective N-monomethylation and selective N,N-dimethylation were accomplished by simply changing the reaction conditions (presence or absence of a base with an appropriate catalyst).

Abstract:

Copper sulfate catalyzed an efficient, inexpensive, and environment-friendly protocol that has been developed for N-arylation of amines with 1,3-cyclohexadione-derived aryliodonium ylides in water as a green solvent. Aromatic primary amines substituted with electron-donating as well as electron-withdrawing groups on the aryl ring reacted smoothly with iodonium ylides to give the corresponding diarylamines with good to excellent yields. Also, secondary amines underwent N-arylation to deliver tertiary amines with moderate yields.

Abstract:

A simple, highly efficient, and environmentally friendly protocol for the synthesis of primary aromatic amines by catalytic coupling of aromatic boronic acids with aqueous ammonia has been developed by using commercial and inexpensive CuSO4·5H2O as catalyst without addition of other solvents under mild reaction conditions.

Abstract:

Batch methanogenic toxicity and biodegradability of 2-, 3- and 4-aminobenzoic acids (ABA) as well as 4- and 5-aminosalicylic acids (ASA) have been studied in the presence of two mesophilic (Shell and cattle) and one thermophilic sludges. The aminoaromatics tested practically did not inhibit methanogenesis up to concentrations of 3–7 g/l; moreover, some of them (2-ABA, 4-ABA and 5-ASA) even exert a stimulating effect on aceticlastic activity of the sludges. Concerning biodegradability, 5-ASA was completely mineralised by all the sludges tested; however, 4-ASA was not degraded at all by any of t

Abstract:

Efficient and general methods for the synthesis of amines remain in high demand in the chemical industry. Among the many known processes, catalytic hydrogenation is a cost-effective and industrially proven reaction and currently used to produce a wide array of such compounds. We report a homogeneous nickel catalyst for hydrogenative cross coupling of a range of aromatic, heteroaromatic, and aliphatic nitriles with primary and secondary amines or ammonia. This general hydrogenation protocol is showcased by straightforward and highly selective synthesis of >230 functionalized and structurally

Abstract:

A new series of substituted 4-biphenylamides have been synthesized by condensation of 4-biphenyl acetic acid with different primary amines (aromatic and aliphatic). 4-Biphenyl acetic acid was first treated with thionyl chloride in dry benzene to prepare substituted 4-biphenyl acetyl chloride, which is then treated with different aliphatic or aromatic amines to synthesize various substituted 4-biphenyl acid-amide derivatives. The structure of newly synthesized compounds has been established by analytical and spectral methods. These synthesized compounds have shown antifungal properties against
