The formation of pentane and anaerobic metabolites of halothane (2-chloro-1,1,1-trifluoroethane and 2-chloro-1,1-difluoroethylene) in a mixture of guinea pig liver microsomes and halothane (2-bromo-2-chloro-1,1,1-trifluoroethane) in the presence of NADPH was studied by gas chromatography. Under anaerobic conditions, pentane was formed without halothane and was inhibited by oxygen tension. This ...

IN THE CRYSTAL STRUCTURE OF THE TITLE ADDUCT [SYSTEMATIC NAME: 2-(1,3-dioxoisoindolin-2-yl)acetic acid-1,3,7-trimethyl-1,2,3,6-tetra-hydro-7H-purine-2,6-dione (1/1)], C(8)H(10)N(4)O(2)·C(10)H(7)NO(4), the components are linked by an O-H⋯N hydrogen-bond and no proton transfer occurs.

1. Three tetracarboxylate porphyrins, apart from coproporphyrin, were isolated from the faeces of patients with symptomatic cutaneous hepatic porphyria and of rats with porphyria caused by hexachlorobenzene poisoning. The porphyrins were not present in the urine of the porphyric rats or in the faeces of control rats. 2. Two of the porphyrins were identified as tris-(2-carboxyethyl)-carboxymethy...

Four new azo-dyes, 3-phenyl azopentane-2,4-dion (LA), 3-(4-nitro phenyl azo)-pentane-2,4-dion (LP), 3-(2-nitro phenyl azo)-pentane-2,4-dion (LO) and 4-(1-acetyle-2-oxo-propyl azo)-benzene sulfonate sodium (LS), were synthesized from, aniline, 4-nitroaniline, 2-nitroaniline and sulfanilic acid with acetylacetone, respectively. Reaction of these new dyes with acetate salts of copper(II), nickel(I...

The reaction of dimethyl acetylenedicarboxylate with OH-acid such as 2-naphthol in the presence of trimethyl or triphenyl phosphite under solvent-free conditions produce oxaphosphaphenanthrene derivatives in good yields. Also, the reaction of dimethyl acetylenedicarboxylate and trimethyl phosphite in the presence of 1-naphthol leads to succinate derivatives in excellent yields. Using triethyl p...

In the title compound, [Ir(C(15)H(9)FNS)(2)(C(5)H(7)O(2))], the Ir atom is hexa-coordinated by three chelating ligands, with two cyclo-metalated 2-(1,3-benzothia-zol-2-yl)-1-(4-fluoro-phen-yl)ethenyl ligands showing N,C-bidentate coordination and an O,O'-bidenate pentane-2,4-dionate anion, thereby forming a distorted octa-hedral enviroment.

The N-H and C=O bonds in the title compound, C(9)H(9)Cl(2)NO(3)S, are trans to each other, similar to what is observed in 2,2,2-trimethyl-N-(phenyl-sulfon-yl)acetamide and 2,2,2-trimethyl-N-(4-methyl-phenyl-sulfon-yl)acetamide. The bond parameters in the title compound are also similar to those in the aforementioned two structures. N-H⋯O hydrogen bonds connect the mol-ecules into chains running...

IN THE TITLE BARBITURATE SALT (TRIVIAL NAME: trimethyl-ammonium 2,4,6-trinitro-phenyl-barbiturate), C(3)H(10)N(+)·C(10)H(4)N(5)O(9) (-), the asymmetric unit contains two sets of anion-cation moieties. The dihedral angle between the rings in the anions are 44.0 (3) and 45.7 (3)°. Adjacent anions are connected into ribbons along [100] through R(2) (2)(8) ring motifs formed by N-H⋯O hydrogen bonds...
