Article abstract of DOI:10.1246/bcsj.65.1188

The treatment of 6b,9a-dihydroacenaphtho<1,2-d><1,2,3>trithiole with 1 equiv of m-chloroperbenzoic acid (mCPBA) affords the corresponding oxidized product, 6b,9a-dihydroacenaphtho<1,2-d><1,2,3>trithiole 7-oxide, as the sole product in 88percent yield, whereas the oxidation using N-halosuccinimide gives 6b,9a-dihydroacenaphtho<1,2-d><1,2,3>trithiole 7,7-dioxide via 6b,9a-dihydroacenaphtho<1,2-d><1,2,3>trithiole 7-oxide.Moreover, the reaction with chloramine T gives a 1,3,2-dithiazolidine derivative in satisfactory yield.
