TL;DR: The cathodic reduction of α,α-dibromodibenzoylmethane (α-bromo-1,3-diphenyl-1-3-propanodione) on Hg and Pt cathodes leads to the same compound but the charge consumption on Pt is double that of Hg as discussed by the authors.

TL;DR: An improved A. O. C. method by dithizone was applied for the determination of mercury residues in rice grains, fruits and tea leaves treated with organomercury fungicides as mentioned in this paper.
Abstract: The dithizone method was applied for the determination of total mercury and organomercury in organomercury fungicides. Paper chromatography was applied for separation and identification of organomercury compounds in fungicide formulation. Gas chromatography with thermal conductivity detector was applied for the determination of D-D, EDB, DBCP, chloropicrin, DDVP, aldrin, dieldrin, chlorobenzilate, BHC isomers, nicotine sulfate, diazinon, heptachlor, VC-13, 2, 4-D ethyl ester, PCP, DBN, DCPA and PCNB in those formulation.An improved A. O. A. C. method by dithizone was applied for the determination of mercury residues in rice grains, fruits and tea leaves treated with organomercury fungicides. The amounts of mercury residues in raw rice grains treated with fungicide ranged from 0.04 to 0.84ppm, and influenced by mainly the lapse days after application. About 60% of mercury residues in raw rice grains was found in pollished grains and remaining 40% was in bran. The more high water solubility and hardly dissociated into ions the compounds has, the more uptake of mercury by rice plant from soil treated with those mercury compounds. Subsequently gas chromatography with electron capture detector was applied for the determination of organochlorine insecticides residues in various crops. The amounts of total BHC residues in raw rice grains treated with BHC dust ranged from 0.41 to 1.42ppm. Afterwards, from the similar purpose, on the relationship between the amounts of DDT and its derivatives residues in rice grains and apples and the history of application were examined under the field conditions.At finally, the biological concentration ratio (BCR) of the fourteen pesticides by fresh water fish, topmouth gudgeon were determined at the equilibrium condition under the continuous flow water system containing about 10ppb of those pesticides. These BCR obtained by this experiment were correlated to the octanol/water partition coefficient of individual compounds and inversely proportional to the water solubility. Therefore, it is able to predict the biological concentration potential of pesticide by means of these two physicochemical properties.

TL;DR: In this article, the authors present a taxonomy of PHENYL and ALKYL-SUBSTITUTED PHENYCLOSES, where the taxonomy can be used in CONTROLLING UNDESIRABLE VEGETATION or in PLANT DEFOLIATION without KILLING the PLANT ITSELF.
Abstract: ORGANOMERCURY COMPOUNDS HAVING THE FORMULA: R-HG-X-C(=X)-N(-R'')-R" WHEREIN R IS PHENYL OR AN ALKYL-SUBSTITUTED PHENYL GROUP HAVING UP TO 12 CARBON ATOMS, R'' AND R" ARE ALKYL GROUPS HAVING UP TO SIX CARBON ATOMS, AND X IS SULFUR WHICH POSSESS HERBITOXIC PROPERTIES. THEREFORE, FORMULATIONS CONTAINING SUCH COMPOUNDS ARE USEFUL IN CONTROLLING UNDESIRABLE VEGETATION OR IN PLANT DEFOLIATION WITHOUT KILLING THE PLANT ITSELF.

TL;DR: Schiff bases are prepared via the reaction of 1,3-propanediamine with isatin in alcohol as discussed by the authors, where the reaction depends on the mode of addition and the obtained data confirmed that the two products are isomers.
Abstract: Schiff bases are prepared via the reaction of 1,3-propanediamine with isatin in alcohol. The reaction depends on the mode of addition. The addition of isatin in alcohol to the diamine in alcohol afforded two products - a major product and a minor one. The obtained data confirmed that the two products are isomers. When the addition was reversed, another product was obtained. As the reaction mixture was left overnight, a product was obtained, which was found to be an isomer. The reaction was repeated in solid state by fusion or in microwave to give the same product. The synthesis, characterization and the reactivity of the Schiff bases with mercury(II) acetate and palladium(ΙΙ) chloride were studied. The structures of the products are confirmed by elemental analyses, IR, UV/Vis, 1 H NMR and mass spectra.
