The crystal structure of the title compound, C(14)H(15)NO·0.5H(2)O, features N-H⋯O and O-H⋯N hydrogen bonds between the amino group and water molecule of crystallization, which generate a chain along the c axis. The water mol-ecule lies on a twofold rotation axis. A C-H⋯π inter-action is observed between the phenyl and aniline rings. The angle between the mean planes of the phenyl rings is 72.5...

Rate and activation parameters for the complex-formation reaction of Ni(2+) with 4-(2-pyridylazo)-N,N-dimethyl aniline (PADA) were studied as a function of pH in different buffers in both aqueous and sodium dodecyl sulfate (SDS) micelle solutions. In aqueous Tris buffer solution, the forward and backward rate constants increased with increasing pH, while the complex-formation constant decreased...

in this study, aniline-formaldehyde polymer was synthesized and then modified with extra aniline as cross-linker in the presence and absence of ni(ii) as the template to produce ion imprinted poly(aniline-formaldehyde) (iipaf) and non imprinted poly(aniline-formaldehyde)(nipaf) the iipaf was subjected to adsorption, preconcentration and determination of ni(ii) ion in environmental samples. the ...

In this study, powder activated carbon (PAC) and magnetic nanoparticles of iron (III) oxide were used for synthesis of Fe3O4-activated carbon magnetic nanoparticles (AC-Fe3O4 MNPs) as an adsorbent for the removal of aniline. The characteristics of adsorbent were evaluated by SEM, TEM, XRD and BET. Also, the impact of different parameters such as pH, contact time, adsorbent dosage, aniline initi...

The first three-component organocatalyzed Strecker reaction operating on water has been developed. The manifold utilizes ketones (aldehydes) as the starting carbonyl component, aniline as the primary amine, acetyl cyanide as the cyanide source and N,N-dimethylcyclohexylamine as the catalyst.

removal of typical contaminants like aromatic amines (e.g. 1-naphthalen amine, diphenyl amine, aniline, 2 and 6-dimethyl pyridine) from water during one-stage process is a method to purify water wherein organic contaminants get extracted from water by bentonite. in this study the effects of ph, stirring time, stirring speed, bentonite mass and bentonite size (mesh) were investigated. also, the ...

An enantioselective four-component reaction of a diazoketone, water, an aniline and ethyl glyoxylate in the presence of catalytic Rh2(OAc)4 and a chiral Brønsted acid was developed to efficiently produce β-hydroxy-α-amino acid derivatives in good yields with high diastereoselectivity and enantioselectivity.

The discovery of two new classes of catalysts for hydrazone and oxime formation in water at neutral pH, namely 2-aminophenols and 2-(aminomethyl)benzimidazoles, is reported. Kinetics studies in aqueous solutions at pH 7.4 revealed rate enhancements up to 7-fold greater than with classic aniline catalysis. 2-(Aminomethyl)benzimidazoles were found to be effective catalysts with otherwise challeng...

Consecutive hydroamination/asymmetric transfer hydrogenation under relay catalysis of an achiral gold complex/chiral Brønsted acid binary system has been described for the direct transformation of 2-(2-propynyl)aniline derivatives into tetrahydroquinolines with high enantiomeric purity.

In order to obtain insight into host responses to grapevine downy mildew (Plasmopara viticola), we compared pathogen development on a panel of Vitis species from North America, Asia and Europe. Leaf discs from different host species were inoculated in parallel, and the colonisation of the mesophyll was visualised by aniline blue staining and quantified with respect to infection incidence and my...
