(57) Abstract: [PROBLEMS] To provide a novel N-substituted phenylcarbamic acid derivative of formula I, a method for producing the same, and an agricultural / horticultural fungicide. The compound of formula III and the compound of formula II are reacted in the presence of a base or a silver compound and in the presence of an inert solvent to give a compound of formula I. (R 1 and R 2 are H, (C1-6) alkyl group, halo (C1-6) alkyl group, (C1-6) alkoxy (C1-6) alkyl group, (C2-6) alkenyl group, (2 -6) Alkynyl group, halo (C1-6) alkoxy Represents a (C1-6) alkyl group or a cyano (C1-6) alkyl group, X represents -O-, -S-, -N (R 4 )-, or -N =, and R 3 represents a phenyl group, a heterocycle condensed with a heterocycle or an aromatic ring, a heterocycle or an aromatic ring, and Fused heterocycle, -C (X 1 -R 5 ) = N- R 6 or -N = C (R 7) indicates R 8, Y represents O or S, R 4, R 5 , R 6 , R 7 , R 8 and X 1 represent specific groups. ) EFFECT compounds of formula I are rice blast shows Inemon blight, powdery mildew, downy high controlling activity ill like. |
