Abstract RU 2626648 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a novel salt of N¹,N¹,N⁴,N⁴-tetramethyl-2-butyn-1,4-diamine with 2-methoxy-3,6-dichlorobenzoate of the corresponding structural formula (1). The compound shows high herbicidal activity, especially when combating annual and perennial dicotyledonous weeds, and can find application in agriculture. The salt corresponds to the structural formula . The invention also relates to a process of preparation of a salt of a compound (1). The method is that the N¹,N¹,N⁴,N⁴-tetramethyl-2-butyn-1,4-diamine with an equimolar amount of an aqueous solution of 2-methoxy-3,6-dichlorobenzoic acid at atmospheric pressure, preferably at a temperature of 20-25°C with stirring for 2.5-3.0 hours. The yield of the product is 85-99%.

EFFECT: new compound is superior in functional activity to a known compound with high selectivity and is effective in controlling weeds in wheat crops.
