Komponenten

Versuchsvorschrift

A mixture of 5.75 g. 3-propylthio-1,2,4-triazole, 6.8 g. diallylcarbamoyl chloride, 25 ml. dry tetrahydrofuran and 8 ml. dry triethylamine was refluxed under anhydrous conditions for 3 hours. The reaction mixture was worked up as described in Example 1 to produce an oil which was distilled under reduced pressure to give 1-diallylcarbamoyl-3-propylthio-1,2,4-triazole, b.p. 134° - 135°C./0.1 mm. Gas-liquid chromatographic (GLC) assay indicated a content of 1-isomer of 94.2%. Elemental analysis satisfactory.
