SALT N,N,N,N-TETRAMETHYL-2-BUTYNE-1,4-DIAMINE WITH N-PHOSPHONOMETHYL GLYCIN, THROUGH HERBICID ACTIVITY AND METHOD OF ITS PRODUCTION Russian patent published in 2017 - IPC C07C211/33 C07C59/70 A01N33/04 A01N39/04 A01P13/00

Abstract RU 2626649 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a novel salt of N¹,N¹,N⁴,N⁴ tetramethyl-2-butyn-1,4-diamine with 2,4-dichlorophenoxyacetate of structural formula (1) having herbicidal activity. The compounds are active especially in relation to annual and perennial dicotyledonous weeds. The compound is a salt corresponding to the structural formula . The invention also relates to a process of preparation of a salt of a compound (1). The method consists in subjecting the N¹,N¹,N⁴,N⁴-tetramethyl-2-butyn-1,4-diamine with an equimolar amount of an aqueous solution of 2,4-dichlorophenoxyacetic acid at atmospheric pressure, preferably at a temperature of 20-25°C and stirring for 2.5-3.0 hours. The yield of the product is 90-99%.

EFFECT: new compound is superior to the herbicidal activity of the known compound.
