The asymmetric unit of the title compound, C(9)H(9)N(2) (+)·C(4)H(3)O(4) (-)·0.5C(4)H(4)O(4), consists of one 2-phenyl-imidazolium cation, one hydrogen fumarate anion and half a fumaric acid mol-ecule, which lies on an inversion center. N-H⋯O and O-H⋯O hydrogen bonds connect the cations, anions and fumaric acid mol-ecules into sheets parallel to the (102) plane.

Aryltellurium trichlorides have proven themselves as good cyclizing reagents in electrophilic intramolecular cyclization reactions, mainly of propenyl derivatives heterocycles. On the other hand, information on use butenyl reactions with p-alkoxyphenyltellurtrichlorides is limited. In this work, regioselectivity process but-2-enyl thioethers quinoline-3carbaldehyde and quinazolin-4-one p-methox...

Novel zinniol-related compound 3, named porritoxin sulfonic acid, with an isoindoline skeleton was isolated from the culture liquid of Alternaria porri. The structure was determined to be 2-(2"-sulfoethyl)-4-methoxy-5-methyl-6-(3'-methyl-2'-butenyloxy)-2,3-dihydro-1H-isoindol-1-one. The phytotoxic activities of three isoindolines (1-3) were evaluated in a seedling-growth assay against stone lee...

Herein, we report the synthesis of two novel coordination polymers using a combination imidazole-containing ligands, namely 1,3,5-tris((1H-imidazol-1-yl)methyl)benzene (L1) and 3,3?,5,5?-tetra(1H-imidazol-1-yl)-1,1?-biphenyl (L2) carboxylate ligand derived from 4,4?-biphenyldicarboxylic acid (H2BPDC). The structures [Ni(L1)(BPDC)]·2H2O (1·2H2O), which exhibits 2-fold interpenetrated 3D ? archit...
