摘要： The present invention relates to a process for the preparation of oxirane compounds of formula II from keto compounds III using dimethyl sulfide (CH3)2S and dimethylsulfate (CH3)2SO4, forming the reagent IV, trimethylsulfonium methylsulfate [(CH3)3S+ CH3SO4−], in aqueous solution in the presence of potassium hydroxide (KOH).
