Synthesis and structural characterization of a new class of pincer type bicyclic diacyloxy- and diazaselenuranes is reported. The reaction of dimethyl 2-bromo-5-tert-butylisophthalate (28) with sodium benzeneselenolate affords the corresponding monoselenide, dimethyl 5-tert-butyl-2-(phenylselanyl)isophthalate (29). Reduction of 29 with LiAlH(4) provides 5-tert-butyl-2-(phenylselanyl)-1,3-phenyl...

Benzothiophene carboxamide derivatives of aminobenzophenone, aminopyridine, aminobenzimidazole, and aniline derivatives (compounds 1-9) were synthesized and compounds 3, 6, 7, 8, and 9 tested in vivo for their hypolipidemic activity. Compounds 1-8 were prepared adopting the fusion process at 130-150 degrees C between benzothiophene-2-carbonyl chloride and aminobenzophenones, aminopyridine, and ...

The reactions of Z-aryl dimethyl (1), methyl phenyl (2), and diphenyl (3) phosphinates with X-anilines in dimethyl sulfoxide at 60.0 °C are studied kinetically. Kinetic results yield the primary normal deuterium kinetic isotope effects (DKIEs) involving deuterated aniline (XC(6)H(4)ND(2)) nucleophiles, k(H)/k(D) = 1.03-1.17, 1.15-1.29, and 1.24-1.51, and the cross-interaction constants (CICs), ...

In the title compound, C(15)H(14)Cl(2)F(3)NO, synthesized by the reaction of 3-[(E)-2-chloro-3,3,3-trifluoro-prop-1-en-yl]-2,2-dimethyl-cyclo-propane-carb-oxy-lic acid and 2-chloro-aniline, the aromatic ring makes a dihedral angle of 76.7 (3)° with the plane of the cyclo-propane ring. In the crystal, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into chains running along the b axis.

In the title compound, C(14)H(14)ClNO(2)S, the angle between the sulfonyl and aniline benzene rings is 65.5 (1)°. The crystal structure features inversion dimers linked by pairs of N-H⋯O hydrogen bonds. The dimethyl-phenyl ring is disordered over two different orientations approximately related by a 180° rotation about the C-N bond, with occupancies of 0.643 (6) and 0.357 (6).

In the mol-ecule of the title compound, C(20)H(19)N(5)O, the pyrazole and oxadiazole rings are not completely conjugated, the dihedral angle between them being 7.97 (6)°. The pyrazole and oxadiazole rings form dihedral angles of 42.74 (6) and 4.35 (5)° with the attached phenyl and benzene rings, respectively.

Symmetric and non-symmetric 2-(N-H, N-methyl, N-ethylenyl and N-aryl)guanidinebenzothiazoles were synthesized from the reaction of ammonia, methylamine, pyrrolidine and aniline with dimethyl benzo[d]thiazol-2-yl-carbonodithioimidate as intermediate. The products were characterized by ¹H-, ¹³C-NMR spectroscopy and three of them by X-ray diffraction analysis. HN-phenyl protons formed intramolecul...

The paper reports the results of studying the kinetics of DGEBA reactions with maleic anhydride catalyzed by N, N-dimethyl aniline (DMA). This stuffs are used as photoelastic model materials. The origination of monoester was studied separately on a model reaction of maleic anhydride with isopropyl alcohol. The subsequent reaction of epoxy groups with monoester was examined on a system of epoxy ...

In the title compound, C(44)H(48)N(6), the essentially planar mol-ecule [maximum deviation from the mean plane of the π system of 0.271 (3) Å] is located on a crystallographic centre of inversion. The almost planar (angle sums at N atoms = 357.6 and 357.1°) dimethyl-amino groups and short C-N bonds of the aniline groups [both 1.379 (4) Å] indicate strong electronic coupling between these groups...

Stevenson, Dobriner, and Rhoads (5) reported that p-dimethylaminoazobenzene when fed to rats is decomposed and metabolized to several simpler compounds. One of these split products, N,N-dimethylp-phenylenediamine, has been found by us ( i ) to be toxic to the glandular epithelium of the rat liver at concentrations of o.oooI M, while equivalent effects on the ductal epithelium were produced only...
