Abstract
Aniline compounds having general formula: ##STR1## wherein A represents an optionally substituted 6-membered heterocyclic group containing one or two nitrogen atoms; p=0 or 1; and Z represents an acyl group of alternatively, when A represents a pyrazinyl group and p is 1, may represent a hydrogen atom; n=0, 1 or 2; and X represents a halogen atom or a group R, OH, OR halogen substituted R, COOH, COOR, NO.sub.2, CN, or NH--CO--NH.sub.2 optionally substituted by R, wherein R is selected from alkyl, alkenyl, alkynyl, cycloalkyl, aryl, aralkyl or alkaryl; or an acid addition salt, N-oxide or metal salt complex thereof, have useful fungicidal, plant growth regulating and herbicidal properties.
Claims4
A compound of the formula ##STR6## wherein the pyridinyl moiety is bonded from a carbon atom thereof to the indicated nitrogen atom, and is optionally substituted by one or two halogen atoms on carbon atoms of the ring;
- p is zero or one;
- n is zero, one or two;
- X is one of halogen, --OH, --COOH, --NO.sub.2, --CN, --NH--C(O)NH.sub.2, --OR, halogen-substituted R, --C(O)OR, and --NH--C(O)NHR, wherein R is phenyl, alkylphenyl, phenalkyl, alkyl, alkenyl, alkynyl, or cycloalkyl wherein the aliphatic moiety contains up to six carbon atoms;
- and Y is alkyl of up to six carbon atoms, or phenyl optionally substituted by halogen, amino or alkyl of up to six carbon atoms;
- or an acid addition salt, N-oxide or metal salt complex thereof.
