The title compound, C(18)H(17)F(2)NO(3), consists of three individually planar subunits, namely two benzene rings and one amino-acrylate group. The amino-acrylate group forms dihedral angles of 5.92 (7) and 50.21 (6)° with the difluoro and methoxy benzene rings, respectively. The dihedral angle between the two benzene rings is 55.25 (7)°. The mol-ecules exhibit intra-molecular N-H⋯O and N-H⋯F i...

In the title compound, C(23)H(17)N(3)O, significant deviations from planarity are evidenced. This is quanti-fied in the dihedral angles formed between the central amino-benzene ring and the benzene rings of the meth-oxy-benzene [67.93 (8)°] and 1,2-dihydro-naphthalene [28.27 (8)°] residues. In the crystal the amino-H atoms form hydrogen bonds to the meth-oxy-O atom and to one of the cyano-N ato...

In the title compound, C(14)H(15)N(3), the diethyl-amino N atom, benzene ring, olefinic bond and cyano groups form an extended conjugated system, making the mol-ecule nearly planar: the dihedral angle between the benzene ring and the best plane throught the cyano groups is 4.93 (10)°, while the dihedral angle between the benzene ring and the plane through the diethyl-amino N atom and the two at...

The title compound, C12H18N4O6S (systematic name: 4-di-propyl-amino-3,5-di-nitro-benzene-sulfonamide), is a sulfonamide with herbicidal properties marketed as oryzalin. The dihedral angles between the benzene ring and the mean planes of the nitro groups are 26.15 (11) and 54.80 (9)°. The propyl arms of the di-propyl-amino substituent lie on opposite sides of this ring plane. In the crystal, N-H...

Cocrystallization of 2-amino-benzothia-zole with benzene-1,2,4-tricarboxylic acid in a mixed solvent affords the title ternary cocrystal, C(7)H(7)N(2)S(+)·C(9)H(5)O(6) (-)·H(2)O, in which one of the carboxyl groups of the benzene-tricarboxylic acid is deproton-ated and the heterocyclic N atom of the 2-amino-benzothia-zole is protonated. In the crystal, inter-molecular N-H⋯O and O-H⋯O hydrogen-b...

The asymmetric unit of the title co-crystalline 1:2 adduct, C(12)H(12)N(2)O(2)·2C(6)H(3)N(3)O(6), contains two independent mol-ecules of bis-(4-amino-phen-yl) sulfone (the drug Dapsone) and four mol-ecules of 1,3,5-trinitro-benzene and is extended into a two-dimensional hydrogen-bonded network structure through amino N-H⋯O hydrogen-bonding associations with nitro O-atom acceptors. In the two in...

A new unsymmetric thioether diamine N - ( 2 - ( 2 - aminophenylthio) ethyl) benzene - 1 , 2 - diamine was prepared through the nucleophilic substitution of cysteaminium chloride with 1 - chloro - 2 - nitrobenzene and then the nitro groups of prepared compuond converted to the amine by zinc powder and ammonium chloride. Then, unsymmetric Schiff bass ligand 2 - ((( 2 - (( 2 - (( 2 - (( 2 - hydrox...

the three components one pot synthesis of 2-amino-4h-benzo-[b] -pyran derivatives were obtained in good to excellent yields within short reaction time by condensing dimedone, aldehydes and malanonitrile or ethylcyanoacetate using a catalytic amount of (diacetoxyiodo)benzene as hypervalent iodine in aqueous ethanol under reflux conditions have been discussed. this aqua mediated knoevenagel-cyclo...

ing with the nitrogen metabolism of mouse epi dermis in various phases of growth and in car cinogenesis (1 to 4). The content of 12 amino acids was determined in dried ground samples of normal ePidermis and epidermis of mice receiving varying numbers of standardized applications of methyl cholanthrene (MC) in benzene (0.6 gm. in 88 gm. of benzene) or of benzene alone. A transplantable squamous ...

OBJECTIVE Human exposure to benzene is associated with multiple adverse health effects with an increased risk of developing carcinogenesis. Benzene exposure is known to affect many critical organs including the hematological, hepatic, renal, lung, and cardiac functions. The purpose of this study is to examine the health effects of benzene exposure among nonsmoking subjects from a prolonged flar...
