abstract The organotin-oxomolybdates [(R3Sn)(2)MoO4] . nH(2)O (R = methyl, n-butyl, cyclohexyl, phenyl, benzyl) have been prepared and tested as catalysts for the oxidation of benzothiophene with aqueous hydrogen peroxide, at 35degreesC and atmospheric pressure. In all cases, the 1,1-dioxide was the only observed product. The kinetic profiles depend on the nature of the tin-bound R group and also on the addition of a cosolvent. For the tribenzyltin derivative, the apparent activation energies for sulfoxidation as a function of the cosolvent are in the order 1,2-dichloroethane (5 kcal mol(-1))
