A process for preparing sulfone derivatives of the formula:
wherein R¹ and R² are each a hydrogen atom, a lower alkyl group or a substituted or unsubstituted cyclo(lower)alkyl, cyclo(lower)alkylmethyl, lower alkenyl, heterocyclic, aryl or ar(lower)alkyl group, R⁴, R⁵, R⁶ and R⁷ are each a hydrogen atom, a lower alkyl group, a lower alkenyl group or a substituted or unsubstituted aryl grcup and Az is a 1,2,4- or 1,3,4-triazole or imidazole ring, which comprises subjecting a sulfide or sulfoxide compound of the formula:
wherein R¹, R², R⁴, R⁵, R⁶, R⁷ and Az are each as defined above and n is an integer of 0 or 1 to oxidation with an oxidizing agent in the presence of a metal catalyst.
