Title compds. (I, R1 = H, ring or chain hydrocarbon; ;R2 = chain or ring hydrocarbon, heterocyclic radical) were prepd. by reaction of trimethylsulfonium methylsulfate with aldehyde or ketone in the presence of bases. Thus, 7.99 g sodium methoxide was added to a mixt. of 17.62 g p-isobutylacetophenone and 28.24 g trimethylsulfonium methylsufate in 100 m1 acetonitrile, and stirred at room temp. for 10 min to give 15.99 g 2-(4'-isobutylpheny1)-2-methyloxirane.
