Title: Reactions of Thianthrene Cation Radical Perchlorate with N-(p-Methoxyphenyl)benzene- and Methanesulphonamides
Abstract:Reactions of thianthrene cation radical perchlorate (1) with N-(p-methoxyphenyl)benzenesulphonamide (14) in acetonitrile at room temperature afforded various products : thianthrene (3), N-(p-hydroxyph...Reactions of thianthrene cation radical perchlorate (1) with N-(p-methoxyphenyl)benzenesulphonamide (14) in acetonitrile at room temperature afforded various products : thianthrene (3), N-(p-hydroxyphenyl)benzenesulphonamide (16), benzenesulphonamide (18), hydroquinone (20); 5-(5-benzenesulphonamido-2-methoxyphenyl)-thia nthrenium perchlorate(21), 2-benzenesulphonamido-2'-hydroxy-5,5'-dimethoxy biphenyl(24), 2-benzenesulphonamido-2',5'-dihydroxy-5-methoxy -biphenyl(25), and a traceable amount of p-quinone(23). The formations of part of (3) and (21) can be explained by either disproportionation or half-regeneration mechanism but those of the remainders by diverse reactions of sulphonamidyl radical (27) derived from (14) (through single electron transfer, followed by deprotonation processes). Similar results were observed from the reaction with N-(p-methoxyphenyl)methanesulphonamide (15).Read More
