Abstract

Abstract A series of 5-(aryl) thianthrenium bromides (6a–e) with aryl (Ar) groups phenyl (a), p- tolyl (b), p-anisyl (c), p-chlorophenyl (d) and p-bromophenyl (e) was prepared by reaction of thianthrene 5-oxide with the appropriate Grignard reagent ArMgBr. Reactions of 6a–e with aryl thiolates (Ar′ SNa, Ar′= phenyl, p-tolyl and p-chlorophenyl, 7a–c) were carried out in MeCN at room temperature. Products from 6a–c were a small amount of arene [benzene ( ...
