In the crystal of the title compound, C(14)H(13)Cl(2)NO(2)S, the N-H bond in the C-SO(2)-NH-C segment is syn to one of the meta-methyl groups in the aniline benzene ring and anti to the other. Further, the conformation of the N-C bond in the C-SO(2)-NH-C segment is gauche with respect to the S=O bonds. The C-SO(2)-NH-C torsion angle is 54.9 (2)°. The sulfonyl and aniline benzene rings are tilte...
In the title compound, C(14)H(16)N(2)O(8)·2H(2)O, the complete organic molecule is generated by crystallographic inversion symmetry. The dihedral angles between the aniline ring and the acetic acid groups are almost identical, viz. 82.61 (7) and 80.33 (7)°. In the crystal, O-H⋯O hydrogen bonds link the organic mol-ecules and water mol-ecules, forming zigzag chains the c axis. An intra-molecular...
In the title compound, C(15)H(14)ClNO, the conformation of the N-H bond is anti to the meta-methyl group in the aniline ring, while that of the C=O bond is anti to the ortho-chloro group in the benzoyl ring. The mean planes through the two benzene rings make a dihedral angle of 80.8 (2)°. In the crystal, mol-ecules are linked by inter-molecular N-H⋯O hydrogen bonds, forming column-like chains a...
Influence of substituent on equilibrium of benzoxazine synthesis from Mannich base and formaldehyde.
N-Substituted aminomethylphenol (Mannich base) and 3,4-dihydro-2H-3-substituted 1,3-benzoxazine (benzoxazine) were synthesized from substituted phenol (p-cresol, phenol, p-chlorophenol), substituted aniline (p-toluidine, aniline, p-chloroaniline) and formaldehyde to study influence of substituent on equilibrium of benzoxazine synthesis from Mannich base and formaldehyde. (1)H-NMR and charges of...
In the title Schiff base, C13H9Cl2NO2, which arose from the condensation of 3,4-di-chloro-aniline with 2,3-di-hydroxy-benzaldehyde, the dihedral angle between the aromatic rings is 44.74 (13)°. Intra-molecular O-H⋯O and O-H⋯N hydrogen bonds close S(5) and S(6) rings, respectively. In the crystal, inversion dimers linked by pairs of O-H⋯O hydrogen bonds generate R 2 (2)(10) loops. A weak C-H⋯π i...
The effects of addition of purified NADPH-cytochrome c (P-450) reductase on microsomal activities of aniline hydroxylation, p-phenetidine O-deethylation and ethylmorphine and aminopyrine N-demethylations were investigated utilizing microsomes from untreated, phenobarbital-treated and 3-methylcholanthrene-treated rats. The purified reductase was incorporated into microsomes. The drug oxidation a...
The conformation of the N-H bond in the structure of the title compound, C(15)H(15)NO, is anti to the ortho and meta-methyl substituents in the aniline benzene ring, in contrast to the syn conformation observed with respect to the ortho and meta-chloro substituents in N-(2,3-dichloro-phen-yl)benzamide. Furthermore, the conformations of N-H and C=O bonds in the amide group are anti to each other...
In the title compound, C(14)H(12)ClNO·0.5H(2)O, the water mol-ecule is located on a twofold axis of symmetry. The meta-Cl atom in the aniline ring is positioned anti to the N-H bond. The two benzene rings make a dihedral angle of 40.40 (11)°. The crystal structure is stabilized by inter-molecular N-H⋯O and O-H⋯O hydrogen bonds, which link the mol-ecules into chains along the a axis.
Two hyperactive mutants of cytochrome c peroxidase (CCP), W51F and W51A, catalyze the enhanced oxidation of a number of substituted anilines. The reaction of CCP compound ES with mesidine is biphasic, while similar reactions using compound II give monophasic kinetics. These data, in addition to the ratio of the Fe4+ = O and free-radical species observed during steady-state turnover, indicate th...
Three of the nine isomeric N-(nitrobenzylidene)iodoanilines, C13H9IN2O2, have been found, when crystallized from acetone, to yield polymorphs which differ from those obtained upon crystallization from ethanol. In the second polymorph of 2-iodo-N-(2-nitrobenzylidene)aniline, the molecules are disordered across inversion centres in space group C2/c, but there are no direction-specific interaction...
