In the mol-ecule of the title compound, C(13)H(8)Cl(3)N, the 4-chloro-aniline and 2,4-dichloro-benzaldehyde moieties are planar with r.m.s. deviation of 0.0115 and 0.0116 Å, respectively, and are oriented at a dihedral angle of 13.94 (8)°.
The title compound, C(10)H(10)Cl(2)N(2)O(2), was prepared by the reaction of ethyl carbazate and 2,4-dichloro-benzaldehyde. In the crystal structure, mol-ecules are linked by inter-molecular N-H⋯O hydrogen bonds, forming extended chains along [001].
The chemical senses may represent the most fundamental integrative sensory modalities. For example, flavor perception is widely considered to be an integrative process whereby two distinct neural systems (olfactory and gustatory) are activated peripherally to give rise to a unitary oral sensation of flavor. Benefits of multimodal sensory integration in other modalities include increased sensiti...
The orthogonal signal correction of Wold algorithm was introduced in this thesis, which was combined with the partial least square algorithm. Calibration model of five components of benzene, methylbenzene, chlorobenzene, benzaldehyde and acetophenone in the mixed liquid samples were developed and validated by the method of independent . The result indicated that the calibration models of the co...
Evaluation of Schiff base nanocomposite hydrogels properties using a benzaldehyde multifunctional amphiphilic polyacrylamide crosslinker in conjunction with glycol chitosan.
In the title 1:1 co-crystal, [PtCl2(C11H14ClN3O)2]·C7H5ClO, the coordination polyhedron of the Pt(II) atom is slightly distorted square-planar with the chloride and 2,3-di-hydro-1,2,4-oxa-diazole ligands mutually trans, as the Pt atom lies on an inversion center. The 4-chloro-benzaldehyde mol-ecules are statistically disordered about an inversion centre with equal occupancies for the two positi...
Hantzsch condensation of two equivalents of methyl-3-aminocrotonate with (m- and p)-methoxybenzaldehyde afforded the expected products 2,6-dimethyl-3,5-dimethoxycarbonyl-4-(m-methoxyphenyl)-1,4-dihydropyridine and 2,6-dimethyl-3,5-dimethoxycarbonyl-4-(p-methoxyphenyl)-1,4-dihydropyridine, whereas o-methoxy-benzaldehyde produced mainly 1-amino-2-methoxycarbonyl-3,5-bis(o-methoxy-phenyl)-4-oxa-cy...
For the first time Knoevenagel condensation has been catalyzed by elemental copper with unexpected activity and excellent isolated yields. Inexpensive, widely available copper powder was used to catalyze the condensation of cyanoacetate and benzaldehyde under mild conditions. To ensure general applicability, a wide variety of different substrates was successfully reacted.
The title compound, C(13)H(10)BrNO, was prepared by reaction of 3-bromo-aniline with 2-hydroxy-benzaldehyde at 377 K. The mol-ecular structure and packing are stabilized by an intra-molecular O-H⋯N hydrogen-bond inter-action.
