| abstract | X für 4-Chlorphenyl, 4-Phenylphenoxy oder 1H-(1, 2, 4)-Triazolyl steht, nlassen sich nach einem neuen Verfahren dadurch herstellen, daß man Dimethylsulfat mit einem Überschuß an Dimethylsulfid behandelt und das dabei entstehende Trimethylsulfonium-methylsulfat der Formeln ohne vorherige Isolierung mit einem Keton der Formeln in welcher X die oben angegebene Bedeutung hat, in Gegenwart von festem Kaliumhydroxid oder Natriumhydroxid in Dimethylsulfid, gegebenenfalls in Gegenwart eines polaren, aprotischen Verdünnungsmittels, bei Temperaturen zwischen 0°C und 50°C umsetzt. Known oxiranes of the formula in which X represents 4-chlorophenyl, 4-phenylphenoxy or 1H- (1, 2, 4) triazolyl, can be prepared by a new process by treating dimethyl sulfate with an excess of dimethyl sulfide and the resulting trimethyl sulfonium methyl sulfate of the formula without prior isolation with a ketone of the formula in which X has the meaning given above, in the presence of solid potassium hydroxide or sodium hydroxide in dimethyl sulfide, optionally in the presence of a polar, aprotic diluent, at temperatures between 0 ° C. and 50 ° C. |
