SIGMA-DELOCALIZED HEXAKIS(METHYLTHIO)BENZENE DICATION - A POSSIBLE INTERMEDIATE OF PUMMERER-TYPE REARRANGEMENT OF MONOOXIDE OF HEXAKIS(METHYLTHIO) BENZENE
K. Kobayashi et al., SIGMA-DELOCALIZED HEXAKIS(METHYLTHIO)BENZENE DICATION - A POSSIBLE INTERMEDIATE OF PUMMERER-TYPE REARRANGEMENT OF MONOOXIDE OF HEXAKIS(METHYLTHIO) BENZENE, Chemistry Letters, (6), 1998, pp. 515-516
The Pummerer-type rearrangement of monooxide of hexakis(methylthio)ben
zene with H2SO4 or (CF3SO2)(2)O gives the cyclic methylsulfonium salt.
A sigma-delocalized hexathia dication is proposed as an intermediate.
