Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
100 words
An N-substituted 2-methylnaphthylamide of the formula ##STR16## where R 1 is --CH(CH 3 )--COOCH 3 , ##STR17## where R 3 and R 4 independently of one another are methyl or ethyl, or R 3 and R 4 together are alkylene of 2 or 3 carbon atoms which is unsubstituted or substituted by methyl or ethyl, and R 2 is a 5-membered heterocyclic ring in which the ring atoms consist of one sulfur atom and one or two nitrogen atoms and is unsubstituted or mono-substituted by methyl, ethyl, bromine, chlorine nitro or di-substituted by one methyl group and one chlorine atom.
Claim 2
Dependent Claim
100 words
An N-substituted 2-methylnaphthylamide of the formula ##STR16## where R 1 is --CH(CH 3 )--COOCH 3 , ##STR17## where R 3 and R 4 independently of one another are methyl or ethyl, or R 3 and R 4 together are alkylene of 2 or 3 carbon atoms which is unsubstituted or substituted by methyl or ethyl, and R 2 is a 5-membered heterocyclic ring in which the ring atoms consist of one sulfur atom and one or two nitrogen atoms and is unsubstituted or mono-substituted by methyl, ethyl, bromine, chlorine nitro or di-substituted by one methyl group and one chlorine atom.
Claim 3
Dependent Claim
127 words
A process for combating fungi, wherein the fungi or the objects to be protected against fungus attack are treated with a fungicidally effective amount of an N-substituted 2-methylnaphthylamide of the formula ##STR18## where R 1 is --CH(CH 3 )--COOCH 3 , ##STR19## where R 3 and R 4 independently of one another or are methyl or ethyl, or R 3 and R 4 together are alkylene of 2 or 3 carbon atoms which is unsubstituted or substituted by methyl or ethyl, and R 2 is a 5-membered heterocyclic ring in which the ring atoms consist of one sulfur atom and one or two nitrogen atoms and is unsubstituted or mono-substituted by methyl, ethyl, bromine, chlorine or nitro or disubstituted by one methyl group and one chlorine atom.
Claim 4
Dependent Claim
127 words
A process for combating fungi, wherein the fungi or the objects to be protected against fungus attack are treated with a fungicidally effective amount of an N-substituted 2-methylnaphthylamide of the formula ##STR18## where R 1 is --CH(CH 3 )--COOCH 3 , ##STR19## where R 3 and R 4 independently of one another or are methyl or ethyl, or R 3 and R 4 together are alkylene of 2 or 3 carbon atoms which is unsubstituted or substituted by methyl or ethyl, and R 2 is a 5-membered heterocyclic ring in which the ring atoms consist of one sulfur atom and one or two nitrogen atoms and is unsubstituted or mono-substituted by methyl, ethyl, bromine, chlorine or nitro or disubstituted by one methyl group and one chlorine atom.
Claim 5
Dependent Claim
40 words
N-substituted 2-methylnaphthylamides of the formula I of claim 1, in which R 2 is isothiazol-3-, -4- or -5-yl, 3-methylisothiazol-4-yl, 3-methylisothiazol-5-yl, 5-nitroisothiazol-3-yl, thiazol-2-, -4- or -5-yl, 2-bromothiazol-4-yl, 2-bromothiazol-5-yl, 5-nitrothiazol-2-yl, 4nitrothiazol-2-yl, 4-methylthiazol-5-yl, 2-chloro-4-methylthiazol-5-yl, 1,2,3-thiadiazol-4-yl, 1,2,3-thiadiazol-5-yl, 5-chloro-1,2,4-thiadiazol-4-yl, 1,2,4-thiadiazol-3-yl, 1,2,4-thiadiazol-5-yl, 1,2,5-thiadiazol-3-yl, 1,3,4-thiadiazol-2-yl or 2-chloro-1,3,4-thiadiazol-5-yl.
