Diphenic acid (H2dip) has been used to synthesize nine homo- or heterometallic uranyl ion complexes under solvo-hydrothermal conditions. The diphenate ligand dip2- adopts different coordination modes, mixtures of κ2-O,O'-chelation by individual carboxylate groups, chelation involving both carboxylate groups, and bridging

Formation of adlayers of the optically active compound 1,1'-binaphthyl-2, 2'-dicarboxylic acid (BINAC) on iodine-modified Au (111) surfaces in perchloric acid was investigated by in situ scanning tunneling microscopy (STM). Highly ordered arrays formed on the surfaces via simple spontaneous adsorption

The ligninolytic fungus Phanerochaete chrysosporium oxidized phenanthrene and phenanthrene-9,10-quinone (PQ) at their C-9 and C-10 positions to give a ring-fission product, 2,2'-diphenic acid (DPA), which was identified in chromatographic and isotope dilution experiments. DPA formation from phenanthrene was somewhat greater

In search of novel anticancer agents, two series of dimethyl [1,1'-biphenyl]-2,2'-dicarboxylate derivatives, 8a-8k and 9a-9k, containing both methylenedioxy and 1,3,4-thiadiazole moieties were designed and synthesized. Cytotoxicity of these compounds was evaluated in vitro against five human tumor cell lines, i.e.
