Реферат: 2-(3-(Substituted alkyl)-benzoyl)-cycloalkan-1-one and -cycloalkane-1,3-dione derivatives are new. Benzoyl-cycloalkan-1-one and benzoyl-cycloalkane-1,3-dione derivatives of formula (I) and their tautomers are new: R<1> = optionally substituted hydrocarbyl optionally containing 1 or more P, O, S, N, F, Cl, Br and/or I atoms; R<2>-R<5> = H; OH; SH; NH2; CN; NO2; halo; or optionally substituted hydrocarbyl optionally containing 1 or more P, O, S, N, F, Cl, Br and/or I atoms; R<6> = OR<12>; Alk-S(O)q; CN; cyanato; SCN; or halo; Alk = alkyl, alkenyl or alkynyl (each optionally substituted with halo); q = 0-2; R<7> = H; tetrahydropyran-(3 or 4)-yl; tetrahydrothiopyran-3-yl; or alkyl, cycloalkyl, alkoxy, alkoxyalkyl, alkylcarbonyl, alkoxycarbonyl, alkylthio or phenyl (each optionally mono- or poly-substituted substituted with halo, alkylthio and/or alkoxy); or two R<7> on the same C atom = -OCH2CH2O-, -OCH2CH2CH2O-, -SCH2CH2S-, -SCH2CH2CH2S- (each optionally substituted with 1-4 CH3 groups); or two R<7> on adjacent C atoms = a bond or together with the C atoms form a 3-6 membered ring optionally mono- or poly-substituted with halo, alkyl, alkylthio and/or alkoxy; R<12> = H; alkyl; haloalkyl; alkoxyalkyl; CHO; alkylcarbonyl; alkoxycarbonyl; alkylaminocarbonyl; dialkylaminocarbonyl; alkylsulfonyl; haloalkylsulfonyl; or benzoyl or phenylsulfonyl (each optionally mono- or poly-substituted with alkyl, haloalkyl, alkoxy, haloalkoxy, halo, CN or NO2); L = 1-2C alkylene optionally mono- or poly-substituted with R<2>; Y = -O-; -S-: -N(H)-; -N(alkyl)-; -CH(R<7>)-; or -C(R<7>)2-; Z' = direct bond; -O-; -S-: -S(O)-; -S(O)2-; -N(H)-; -N(alkyl)-; -CH(R<7>)-; or -C(R<7>)2-; v = 1 or 2; w = 0-4. Compounds are excluded when L-R<1> = optionally substituted benzyl, R<2> = R<3> = Cl and R<4> = R<5> = H.
