indandione 1 was brominated to yield 2-bromoindandione 2 which on further reacted with substituted thiocarbamides, carbamides, 2-aminothiophenols, 2-aminophenol and triazoles to furnished 3-substituted aniline-2-thia-4-aza-6,7-benzo-8-oxo-bicyclo [3.3.0]-1(5),3-octadiene 3, 3-substituted aniline-2-oxa-4-aza-6,7-benzo-8-oxo-bicyclo [3.3.0]-1(5),3-octadiene 4, 2-thia-5-aza-9-oxo-3,4-(3’-substitut...

Aniline-induced splenic toxicity is characterized by hemorrhage, capsular hyperplasia, fibrosis, and a variety of sarcomas in rats. Early biochemical events responsible for the observed effects are not known. To understand the mechanism(s) of aniline-induced splenic toxicity, single and multiple (four and seven) doses of 1 mmol/kg of aniline hydrochloride(AH) were given in rats. Apart from chan...

There are two mol-ecules in the asymmetric unit of the title compound, C(11)H(9)ClN(2), with dihedral angles of 41.84 (12) and 49.24 (12)° between the aromatic ring planes. The two mol-ecules form a dimer via a pair of N-H⋯N hydrogen bonds.

In the title mol-ecule, C(15)H(15)ClN(2), the dihedral angle between the aromatic is 64.1 (2)°.

In the title fluorinated pyrrolidine derivative, C(10)H(10)F(4)N(2), the dihedral angle between the best planes of the benzene and pyrrolidine rings is 62.6 (1)°. The crystal packing features inter-molecular N-H⋯F hydrogen bonds.

In the title compound, C(15)H(14)N(2)O(2), the 2,3-dimethyl-anilinic and benzaldehyde groups are planar, with r.m.s. deviations of 0.0101 and 0.0241 Å, respectively, and are oriented at a dihedral angle of 11.69 (3)°. The nitro group is inclined to the benzaldehyde group by 34.02 (9)°. The mol-ecule adopts an E configuration about the C=N bond. In the crystal, mol-ecules are linked via C-H⋯O in...

The mol-ecule of the title compound, C(10)H(13)Br(2)N, has a twofold rotation axis along the N-C(phen-yl) bond. The compound shows a slightly distorted trigonal planar geometry around the N atom. The structural study shows the presence of inter-molecular C-H⋯Br inter-actions, resulting in a three-dimensional supra-molecular architecture.

The title compound, [Fe(C(5)H(5))(C(13)H(9)F(3)N)], was prepared by a condensation reaction from ferrocenylcarbaldehyde and 4-(trifluoro-meth-yl)aniline. The cyclo-penta-dienyl (Cp) rings are coplanar [dihedral angle = 1.4 (3)°] and the imine function is situated in the same plane. The aromatic substituent is bent out of the plane of the Cp ring to which the imine group is attached by 44.5 (4)°...

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...

The two aromatic rings in the title compound, C(10)H(8)ClN(3), open the angle at the planar N atom to 128.00 (12)°. The amino N atom of one mol-ecule forms a hydrogen bond to the 1-N atom of an adjacent pyrimidyl ring, generating a hydrogen-bonded dimer.
