SUBSTITUTED NAPHTHALENE-1,4-DINS POSSESSING PESTICIDE PROPERTIES, METHOD OF PREPARATION THEREOF, UTILIZATION THEREOF AS PESTICIDES, PEST CONTROL METHOD INVOLVING THESE COMPOUNDS, AND PESTICIDE COMPOSITION INCLUDING THEM Russian patent published in 2001 - IPC

FIELD: biologically active compounds. SUBSTANCE: invention provides novel substituted naphthalene-1,4-dions, which can be used as insecticides against whitefly. Compounds are depicted by general formula I: (I), wherein n= 0, m=0, R¹ and R², taken together, form oxo group; R³ denotes hydroxyl group or group -OCOR¹¹, in which R¹¹ is C1-alkyl; R⁷ and R⁸, taken together, form oxo group; R⁴ and R⁵, independently from each other, denote hydrogen atom or methyl or, taken together with carbon atom, to which they are linked, form C4- C8-cycloalkyl ring, 4-tert-butylcyclohexyl ring, full number of carbon atoms in most long carbon chain in position 3 of naphthalene cycle not exceeding 2. EFFECT: enhanced pesticide activity. 37 cl, 6 tbl, 5 ex
