E. Dumitriu et al., Heterogeneous sulfoxidation of thioethers by hydrogen peroxide over layered double hydroxides as catalysts, CATAL TODAY, 66(2-4), 2001, pp. 529-534
A new method for mild oxidation of thioethers with hydrogen peroxide in het
erogeneous catalysis is described. The layered double hydroxides (or hydrot
alcite-like materials) act as basic catalysts for the sulfoxidation reactio
n with hydrogen peroxide in the presence of acetonitrile. The influence of
the nature of thioether, the type of catalyst, the reaction temperature and
reaction time on the catalytic activity and selectivity in this reaction h
as been investigated. A mechanism of the sulfoxidation reaction is proposed
