In the title compound, C14H9Cl2N3O4·C3H7NO, the hydrazone mol-ecule adopts an E conformation with respect to azomethine bond, and the dihedral angle between the two aromatic rings [8.96 (11)°] shows that the rings are almost co-planar. The planar conformation of the mol-ecule is stabilized by the intra-molecular O-H⋯N hydrogen bond involving the OH group and azomethine N atom. The azomethine an...

The asymmetric unit of the title compound, C15H13N3O3·H2O, comprises a 4-{(E)-[2-(pyridin-4-ylcarbon-yl)hydrazinyl-idene]meth-yl}phenyl acetate mol-ecule and a solvent water mol-ecule linked by O-H⋯O and O-H⋯N hydrogen bonds from the water mol-ecule and a C-H⋯O contact from the organic mol-ecule. The compound adopts an E conformation with respect to the azomethine bond and the dihedral angle be...

The title compound, C20H18N2S, was synthesized by the condensation reaction between p-tolu-idine and thio-phene-2,5-dicarboxaldehye in refluxing toluene with p-toluene-sulfonic acid added as catalyst. The mol-ecule lies on a twofold rotation axis and adopts an E orientation with respect to the azomethine bonds. The dihedral angle between the unqiue benzene ring and the least-squares plane [maxi...

A highly reactive Ag(I)-catalyzed [3 + 2] cycloaddition of azomethine ylides is founded using AgOAc as the catalytic precursor and phosphines as ligands. Using a new bis-ferrocenyl amide phosphine (FAP) as the ligand, we found that high enantioselectivities (up to 97% ee) have been achieved in the [3 + 2] cycloaddition of azomethine ylides. Up to four stereogenic centers can be established in t...

The title compound, C(16)H(11)ClN(2), displays a trans configuration across the C=N bond and a transoid arrangement across the quinoline ring and the azomethine C atom. This arrangement facilitates C-H⋯Cl interactions. The packing in the crystal structure is due to inter-molecular C-H⋯π and Cl⋯π (3.52 and 3.84 Å) inter-actions. The dihedral angle between the least-squares planes of 2-chloro-qui...

Trifluoromethylated pyrrolidines have been synthesized via catalytic asymmetric 1,3-dipolar cycloaddition with excellent stereoselectivity for the first time. Epimerization of the endo-pyrrolidines obtained from cis-4,4,4-trifluorocrotonate into the exo-pyrrolidines was also revealed.

A new series of pyrrolo[3',4':3,4]pyrrolo[1,2-a]furoquinolines/phenanthrolines and pyrrolo[1,2-a]phenanthrolines were efficiently built up from an 8-hydroxyquinoline derivative or phenanthroline via 1,3-dipolar cycloaddition reaction involving non-stabilized azomethine ylides, generated in situ from the parent furo[3,2-h]quinoliniums/phenanthroliums, in presence of a copper(II) chloride-phenant...

An effective and highly regio- and diastereoselective one-pot method for the synthesis of new polynuclear dispiroheterocyclic systems with five stereogenic centers (dispiro[imidazo[4,5-e]thiazolo[3,2-b]-1,2,4-triazine-6,3'-pyrrolidine-2',3''-indoles]) comprising pyrrolidinyloxindole and imidazo[4,5-e]thiazolo[3,2-b]-1,2,4-triazine moieties has been developed. The method relies on a 1,3-dipolar ...

In this data article, ITO/AZO/Ge photodetector was investigated for electrical circuit model. Due to the double (ITO and AZO) transparent metal-oxide films (DOI:10.1016/j.mssp.2016.03.007) (Yun et al., 2016) [1], the Ge heterojunction device has a better interface quality due to the AZO layer with a low electrical resistance due to the ITO layer (Yun et al., 2015) [2]. The electrical and interf...

p-Dimethylaminoazobenzene (DAB) is an azo-dye and known to cause liver tumour in rats. Azo-dye binding protein is a specific cytosolic protein involved in the translocation of azo-dye carcinogen metabolites from liver cytoplasm into the nucleus. Administration of vitamin A (40,000 and 50,000 IU), L-ascorbic acid (500 and 1000 mg) and vitamin E succinate (200-500 mg) reduced the amount of azo-dy...
