ABSTRACT: Arylthiols were reacted with acrylonitrile under basic conditions to form
the corresponding aryl sulfides which were oxidised with sodium metaperiodate in aqueous
methanol to yield 3-arylsulphinylpropanenitriles that upon thermolysis in
refluxing toluene produced a mixture of diarylthiosulfonates and
diaryldisulfides. The mixture of the two
products was easily separated by flash chromatography
and characterized spectroscopically. The diarylthiosulfonates and diaryldisulfides, garlic-like organosulfur
compounds, were tested for their antimicrobial properties against Escherichia
coli, Pseudomonas aeruginosa, Staphylococcus aureus and Helicobacter pylori and had been found to have good activity against S. aureas and H. pylori with no activity against the other two
organisms.
