Poly(amide amine) dendrimer with naphthyl units (N8) as a fluorescent chemosensor for metal ions was synthesized. We investigated the metal ion recognition of N8. Large changes in the fluorescence spectra of N8 were observed upon the addition of cadmium and zinc ions.

The title compound, C(25)H(22)N(2)O(3), was synthesized by the reaction of 3-nitro-benzaldehyde, dimedone and 2-naphthyl-amine in ethanol. In the mol-ecular structure, the cyclo-hexenone ring adopts an envelope conformation, whereas the piperidine ring has a boat conformation. The crystal packing is stabilized by inter-molecular N-H⋯O hydrogen bonds.

We describe a new type of nitrogen-centered polycyclic scaffold comprising unique combination 5-, 6-, and 7-membered rings. The compound is accessible through an intramolecular oxidative cyclodehydrogenation tri(1-naphthyl)amine. To the best our knowledge this very first example direct 3-fold cyclization triarylamine under conditions. unusual ring fusion motif confirmed by X-ray crystallography...

von Braun Cyanogen Bromide Reaction Some extensions of von Braun cyanogen bromide reaction have been undertaken on conessine, isoconessine and two simpler bases, dimethyl a-naphthyl amine and diethyl amine. The monocyanamides of conessine and isoconessine yielded acid amides, aminoderivatives (diamines) and guanido derivatives on careful hydrolysis, reduction and treatment with ammonia, respect...

Abstract Here, we present a thorough structural study of small, easily accessible amino−organolithium compounds with bridging phenyl and naphthyl moieties. Their crystal structures most likely represent their aggregation as tetramers dimers in both hydrocarbon ethereal solvents. These were further used to generate corresponding aluminium model system. are reported too. All discussed focus on th...

The title compound, C(15)H(15)NO, which was synthesized under solvent-free conditions by the reaction of acetoacetone and 2-naphthyl-amine, adopts a Z conformation about the C=C bond. The enamine-ketone fragment is approximately planar [maximum deviation = 0.026 (3) Å] and forms a dihedral angle of 39.78 (3)° with the naphthalene ring system. An intra-molecular N-H⋯O hydrogen bond is observed.

A poly(amine ester) dendrimer with naphthyl units (G1N6) has been synthesized as a fluorescent chemosensor for metal ions. We investigated the metal-ion recognition of G1N6 by adding each of Ag(+), Al(3+), Ba(2+), Ca(2+), Cd(2+), Co(2+), Cu(2+), Fe(3+), Mg(2+), Ni(2+), and Zn(2+) in acetonitrile solution. Large changes were observed in the fluorescence spectra of G1N6 upon the addition of Al(3+...

Для определения энтальпий образования радикалов нафталина (нафтил-1 и нафтил-2) применили метод двойной разности. Получены для нафтил-1 нафтил-2 одинаковые энтальпии 405,0 ± 2,0 кДж∙моль. Эти величины использовали корректировки имеющихся производных в газовой фазе. Энтальпии позволили рассчитать энергии диссоциации связей D(С - NO2) 1- 2-нитронафталине, которая составила 306 кДж·моль. идентично...
