Abstract:
Abstract The reactions of dichloroalkanes and sodium tetra-sulfide (Na2S4) were carried out in a mixture of water and toluene to produce corresponding cyclic polysulfides and polysulfide polymer. The low molecular weights of cyclic sulfides were obtained by the reaction at 90 °C, while the high molecular weight of polysulfide polymer was obtained by the reaction at 50 °C. GPC chromatograms and Mass spectra revealed that the structures of cyclic polysulfide were 1:1, 2:2, and 3:3 adducts of dichloroalkane and sodium tetra-sulfide.

Abstract:
The reaction of 1-alkynyl sulfides and alkynyl sulfoxides with Et3Al under zirconocene catalysis conditions has been studied. The interaction between 1-alkynyl sulfides and Et3Al in the presence of catalytic amounts of Cp2ZrCl2 leads to trisubstituted 1-alkenyl sulfides in moderate to good yields (56–73%) with high regioselectivity and stereo­selectivity. 1-Alkynyl sulfoxides, upon treatment with Et3Al under the same reaction conditions, undergoes reduction to give sulfides. The excess of Et3Al (7 equiv) in this reaction causes cyclic carboalumination of in situ generated 1-alkynyl sulfide to

Mercury (Hg) is a toxic heavy metal that poses significant human and environmental health risks. Mineral-associated Hg is the largest reservoir of Hg in the environment where it can account for nearly 60% of the global Hg mass inventory. A large fraction of this pool is comprised of mercury sulfide (HgS) minerals, including metacinnabar (beta-HgS). HgS minerals have long been considered insignificant sources of Hg to aqueous or atmospheric pools in all but severely acidic environments due to their low solubility and slow abiotic dissolution kinetics.

During organic material degradation in oxic environments, electrons from organic material, the electron donor, are transferred to oxygen, the electron acceptor, during aerobic respiration. Other compounds, such as nitrate, iron, sulfate, and carbon dioxide, take the place of oxygen during anaerobic respiration in anoxic environments. The order in which these compounds are used by bacteria and archaea (only a few eukaryotes are capable of anaerobic respiration) is set by thermodynamics.
