Proton-ligand dissociation and metal-ligand stability constants of trithiocarbodiglycolic acid (TCGA) with some transition metal ions were calculated potentiometrically.The order of stability constants was found to be Fe(3+) > Cu(2+) > Ni(2+) > Co(2+).The effect of temperature on the stability of the complexes formed was studied and the corresponding thermodynamic functions were derived and discussed.Polarographic and cyclic voltammetric behaviours of TCGA were investigated in B.R. buffer solutions of pH 2-12.In solutions of pH 8, the polarograms and cyclo-voltammograms exhibited a single 2-electron diffusion-controlled irreversible step, corresponding to the reduction of the C=S.The mechanism of the reduction process was postulated and the kinetic parameters of the electrode process were evaluated. - Keywords.Trithiocarbodiglycolic acid; Dissociation and stability constants; Thermodynamics; Potentiometry; Polarography; Cyclic-voltammetry.

A novel method is reported for the synthesis of symmetric dialkyl and cyclic (5, 6 and 7 member) trithiocarbonates from alkyl halides and carbon disulfide in the presence of imidazole and water in DMSO under mild reaction conditions. Imidazole is used as an inexpensive, non-toxic and readily available catalyst in this procedure.

-
, (2008/06/13)
Pesticidal composition comprising: a pesticidal, phosphoric ester the molecule of which has at least one alkyl group of 1 to 3 carbon atoms, 0.05 to 10% of an agent stabilizing the said ester against decomposition by protonisation, together with adjuvants characterized in that the stabilizing agent comprises at least one sulphur compound containing per molecule at least one divalent sulphur atom of which one valence is bonded to an atom chosen from sulphur, carbon, nitrogen, hydrogen, and metals capable of giving a salt, the other valence being bonded to an atom chosen from hydrogen, the carbon atom already noted, a second carbon atom, the nitrogen atom already noted, a second nitrogen atom, the metal atom already noted in the case of a metal of valence greater than one, a second atom of metal and oxygen when the first valence is not attached to an atom of hydrogen, the proportion of sulphur calculated with reference to the weight of the sulphur compound being between 5 and 99%. Process for stabilizing a phosphoric ester of which the molecule possesses at least one alkyl group containing 1 to 3 carbon atoms characterized in that there is added to the phosphoric ester or to a mixture which contains it, 0.05 to 10% calculated on the weight of the phosphoric acid ester of an agent capable of stabilizing the said phosphoric ester against protonisation and comprising at least one sulphur compound such as that defined thereupon.
