Abstract: The invention relates to a novel method of producing the compounds of formul a (I) wherein the substituents have the following meanings: n is 0,1 or 2; R1, R2 represent C1-C6-alkyl; R3, R4, R5 are hydrogen, C1-C6-alkyl or R4 and R5 together form a bond; R6 is C1, Br. Said method comprises the following step s: a synthesis sequence starting from 1,2-dialkylbenzenes of formula (II); halogenation to form 3,6-dihalogen-1,2-dialkylbenzenes; haloalkylation to fo rm benzyl bromides; oxidation to form benzaldehydes; reaction with alkenes to form isoxazoles; reaction to form thioethers and optionally oxidation to for m sulfenyl or sulfonyl derivatives of formula (I).
