TRIAZINONE DERIVATIVES, HERBICIDE COMPOSITION, METHOD OF WEEDS ABOLISHING Russian patent published in 1995 - IPC

FIELD: organic chemistry. SUBSTANCE: products: derivatives of triazinone of the formula (I) where R-C₁-C₄-alkyl, R¹-C₁-C₄-haloidalkyl, Q-CH(R²)C(R³)(R⁴)Q′ or CH = C(R⁴)Q′; R² hydrogen, halogen; R³ halogen; R⁴ hydrogen or lower alkyl, Q¹-CO₂H, CO₂R⁵, CON(R⁶)(R⁷)CN, CHO, COR₅ where R⁵-C₁-C₄-alkyl, benzyl, each R₆ and R₇ independently each of other is hydrogen or radical C₁-C₄-alkyl, cyclopropyl, C₂-C₄-alkenyl, C₁-C₄-alkoxy, phenyl, C₁-C₄-alkoxycarbonyl-C₁-C₄-alkyl, benzyl or SO₂R⁶. R⁶ differs of hydrogen or one of indicated radicals substituted with halogen atom, lower alkyl, cyano or salt of this compound base where Q′-CO₂H. Herbicide composition prepared on the basis of derivative of the formula (I) at concentration 10-90 wt.-% and a method of weeds abolishing using compound of the formula (I) at concentration 0.0625-0.5 kg/ha. Synthesized compounds were used in agriculture for chemical treatment of plants. EFFECT: improved method of synthesis. 5 cl, 4 tbl
