Thioxanthen-9-one

The DszC enzyme was able to convert the following compounds other than DBT thioxanthen-9-one, 2,8-dimethyl DBT, 4,6-dimethyl DBT, and 3,4-benzo DBT. Non-organosulfur compounds such as biphenyl, carbazole, and dibenzofuran did not show any activity. This indicates that dszC specifically recognizes sulfur atom [151]. One study specifically examined the DszC enzyme for oxidation of aryl sulfides [179] and reported oxidation of many sulfides including, naphthyl methyl sulfide, phenyl methyl sulfide, and its alkyl derivatives.

The ketyl radicals of thioxanthen-9-one (166) and -9-thione (167) have been described by several groups, and various ion-pairing phenomena were reported.The hyperfine splittings indicated in gauss, for the ion-pair of 166 with potassium in DME are those of Urberg and Kaiser, and those for the ion-pair of (167) with sodium in the same solvent are due to Aarons and Adam, who found a marked temperature dependence of the counterion hyperfine splittings that indicated is for 23°C.

A solution containing 3-allyl-3-methyl-l,2-diphenylcyclopropene (100 mg, 0.41 mmol) and thioxanthen-9-one (100 mg) in benzene (150 mL) was irradiated under an argon atmosphere for 1 h with a 450-W Hanovia arc lamp equipped with a uranium glass filter sleeve. The mixture was concentrated under reduced pressure to a volume of approximately 10 mL and column chromatographed (silica gel, hexane). Removal of the solvent under reduced pressure left 70 mg (70%) of a colorless oil which was identified as the title compound.
