Mixtures of sulfides and disulfides are obtained upon reaction of boron trisulfide with a series of allyl aryl suit oxides, with the product distributions dependent upon the structures of the intermediate thiosulfoxides.

Syntheses of RC6F4SR′ compounds (where R = F, C6F5, H, R′ = alkyl, trifluorovinyl) have been accomplished through reaction between ArfSM (where M = Cu, MgX) and an alkyl or trifluorovinyl halide in dimethylacetamide solvent. Minor by-products from competing reactions have been partially characterized by GC-MS analysis.

Photoreaction of pentafluorophenyl-prop-2-enyl ether in cyclohexane at λ = 253.7 nm resulted in intramolecular [2+2] cycloaddition, forming 2,3,4,5,6-pentafluoro-1,8-epoximethano bicyclo[4.2.0]octa-2,4-diene, while a similar reaction of the thio analogue led to C—S bond cleavage.
