The catalytic methyl-transfer reaction from methyl tosylate to 1-octanethiol was carried out in the presence of a simple vitamin B12 model complex, [Co(III){(C2C3)(DO)(DOH)pn}Br 2], with zinc powder as the reducing reagent at 50°C. Such a catalytic reaction proceeded via the formation and dissociation of a cobalt-carbon bond in the simple vitamin B12 model complex under non-enzymatic conditions. The mechanism for the methyl-transfer reaction was investigated by electronic and mass spectroscopies. The Co(I) species, which is generated from the reduction of the catalyst by the zinc powder, and its methylated CH3-Co complex were found to be indispensable intermediates.

A new procedure for the synthesis of aryl methyl sulfides from dimethyl carbonate (DMC) and arylsulfonyl chlorides has been achieved. In this strategy, DMC plays a dual role as both, C1 building block and green solvent. Arylsulfonyl chlorides served as the sulfur precursors, and a variety of aryl methyl sulfides were obtained in moderate to excellent yields with good functional group tolerance. Additionally, alkylsulfonyl chloride and dibenzyl carbonate are proven to be suitable substrates as well.

Paragraph 0038; 0039, (2018/11/22)
The invention belongs to the technical field of chemical synthesis and application of chloramine antibacterial agents, and provides a sulfonium salt type chloramine antibacterial agent and a syntheticmethod thereof. A preparation method of the antibacterial agent comprises the following steps: taking bromoalkyl 5,5-dimethylhydantoin and thioether as raw materials to prepare a sulfonium salt bromide chloramine precursor compound IV; reacting the precursor compound IV with t-butyl hypochlorite at normal temperature after ion exchange to obtain an antibacterial agent compound I. The antibacterial agent disclosed by the invention introduces a cationic structural unit-sulfonium salt group into a hydrophobic chain chloramine group, so that water solubility of the chloramine antibacterial agentis greatly improved and structure stability of the chloramine antibacterial agent is significantly enhanced. By using staphylococcus aureus as a model strain, the antibacterial test result shows thatthe bactericidal activity of the prepared sulfonium salt type chloramine compound is better than that of a mono-quaternary ammonium salt type chloramine compound.

The first demonstration of the hydrogenation of sulfoxides under atmospheric H2 pressure is reported. The highly efficient reaction is facilitated by a heterogeneous Ru nanoparticle catalyst. The mild reaction conditions enable the selective hydrogenation of a wide range of functionalized sulfoxides to the corresponding sulfides. The high redox ability of RuO x nanoparticles plays a key role in the hydrogenation.
