Triethylamine → 4-Allyl-5-trifluoromethyl-3-(1,2-dichloro-2-cyanovinyl thio)-1,2,4-triazole

Participants

Reaction Steps

A mixture of 4.0 g (0.019 mole) 4-allyl-5-trifluoromethyl-3-mercapto-1,2,4-triazole (the product of Example 2), 3.0 g (0.019 mole) trichloroacrylonitrile (the product of Example 3A), and 2.65 ml (0.019 mole) triethylamine in 100 ml methylene chloride was stirred at room temperature for several days. The reaction mixture washed with water, dried over magnesium sulfate, and stripped to give a yellow oil. Further purification by chromatography gave 3.6 g of the product as an oil which later crystallized, melting point 45°-48° C.
