THE TITLE COMPOUND [SYSTEMATIC NAME: 4-diphenyl-methyl-1-(3-phenylprop-2-en-1-yl)-piperazin-1-ium 2-carb-oxy-4,6-dinitro-pheno-late], C(26)H(29)N(2) (+)·C(7)H(3)N(2)O(7) (-), is the dinitro-salicylate salt of a tertiary amine. Deprotonation of the carb-oxy-lic acid group occurred on the phenolic hy-droxy group. The diaza-cyclo-hexane ring adopts a chair conformation. Intra-molecular O-H⋯O and i...
The title compound, C(12)H(8)N(2)O(5), was obtained by the reaction of 1-chloro-2,4-dinitro-benzene and phenol in the presence of potassium carbonate. The nitro-substituted benzene ring lies on a mirror plane, with one NO(2) group in the same plane and the other disordered across this plane. The phenoxy-benzene unit is placed perpendicular to this mirror, resulting in an exact orthogonal relati...
The herbicide 4,6-dinitro-o-cresol inhibits electron transport to ferricyanide and non-cyclic photophosphorylation for 50% at about 15 /am. At higher concentrations the photosystem I depen dent M ehler reaction ascorbate/dichlorophenolindophenol to methyl viologen is stimulated, while cyclic photophosphorylation is inhibited. The herbicide thus is an inhibitory uncoupler. Although the chemical...
Two independent mol-ecules comprise the asymmetric unit of the title compound, C(12)H(11)N(3)O(2). These differ in terms of the relative orientations of the benzene rings as seen in the respective dihedral angles formed between the pyridine and benzene rings [17.42 (16) and 34.64 (16)°]. Both mol-ecules are twisted about the amine-tolyl N-C bonds [respective torsion angles = 22.3 (5) and 35.9 (...
2-Sulfanyl-6-(2-thienyl)pyridine-3-carbonitrile, 1-Amino-6-(5-bromo-benzofuran-2-yl)-2-oxo-1,2-dihydro-pyridine-3-carbonitrile, thieno[2,3-b]pyridins, pyrimidino[4',5':4,5] thieno[2,3-b]pyridine, quinazoline and carbamate derivatives were synthesized from sodium 3-(5-bromobenzofuran-2-yl)-3-oxoprop-1-en-1-olate with. The newly synthesized compounds were elucidated by elemental analysis, spectra...
