CARBAMATES, INTERMEDIATE COMPOUNDS, A FUNGICIDE COMPOSITION, A METHOD OF STRUGGLE AGAINST FUNGI Russian patent published in 1999 - IPC

FIELD: organic chemistry, fungicides. SUBSTANCE: invention proposes carbamates of the formula (I) OCH₃,NH₂,NHCH₃,N(CH₃)₂,CH₃,C₂H₅,CF₃ where Z means and CCl₃; X and Y mean hydrogen atom, F, Cl, Br, alkyl; R¹ means hydrogen atom, alkyl, halogen-substituted alkyl, alkenyl, alkynyl, alkoxy-group and the others; A means -O-, -CH₂-, -CH=CH-, -CH₂O-, -CH=N-O- and the others; B means unsubstituted phenyl or phenyl substituted with alkyl, halogen atom, nitro-group, phenyl and the others, 5- or 6-membered aromatic ring containing 1-3 atoms of nitrogen, sulfur or oxygen with one or two nitrogen atoms being heteroaromatic ring can be substituted with alkyl, haloidalkyl, isoxazole and the others, and their active salts of acids or bases that are compatible with plants. Intermediate derivatives of benzene of the formula E where X and Y are alkyl; Q means NO₂,NH₂,NHOR¹,NHR¹, NCO, NR¹COZ where Z means methoxy- -group, NHCH₃ and R¹ is hydrogen atom or alkyl; A means -CH₂O-,-CH₂ON=CH(CH₃),-CH₂ON=CH(C₂H₅);; B means unsubstituted phenyl or phenyl substituted with alkyl, halogen atom, -C(R³)=NOR³ where R³ - alkyl or alkenyl. Derivatives of benzene of the formula F where X and Y - hydrogen, halogen atoms or alkyl; Z means groups OCH₃,CH₃,NHCH₃; R¹ and R² - hydrogen atom or alkyl; T means hydrogen or halogen atom. Derivative of benzene of the formula G where X and Y - hydrogen atom; Z means CH₃,C₂H₅,OCH₃; A means a simple bond and B is alkyl. Invention relates to also a fungicide composition and a method of struggle against fungi by treatment of plants with fungicide composition based on N-phenylcarbamic acid. EFFECT: improved method of synthesis, enhanced effectiveness of fungicide composition. 76 cl, 59 tbl, 25 ex
