Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
90 words
A compound of the formula: ##STR8## wherein rings A and B are unsubstituted, or carry one or more substituents, each substituent being a lower alkyl radical; a fluorine, chlorine, bromine, or iodine atom; a lower alkoxy radical; a cyano group; a nitro group; a lower alkylcarbonyloxy radical; a methylenedioxy radical; an amino group; or a mono- or di- lower alkyl substituted amino group, and wherein Het stands for a 1,2,4-triazol-1-yl radical, at least one of the rings A and B being substituted; and salts of compounds of the foregoing formula.
Claim 2
Dependent Claim
90 words
A compound of the formula: ##STR8## wherein rings A and B are unsubstituted, or carry one or more substituents, each substituent being a lower alkyl radical; a fluorine, chlorine, bromine, or iodine atom; a lower alkoxy radical; a cyano group; a nitro group; a lower alkylcarbonyloxy radical; a methylenedioxy radical; an amino group; or a mono- or di- lower alkyl substituted amino group, and wherein Het stands for a 1,2,4-triazol-1-yl radical, at least one of the rings A and B being substituted; and salts of compounds of the foregoing formula.
Claim 3
Dependent Claim
16 words
Compounds as claimed in claim 1 wherein ring A is unsubstituted and ring B is substituted.
Claim 4
Dependent Claim
15 words
Compounds as claimed in claim 2 wherein ring B carries a 2-chloro or 2-fluoro substituent.
Claim 5
Dependent Claim
44 words
Salts of compounds as claimed in claim 1, wherein the salts are formed from alkali metals, alkaline earth metals, ammonia, or primary, secondary, or tertiary aliphatic amines in which the 1, 2 or 3 aliphatic radical each contain from 1 to 6 carbon atoms.
Claim 6
Independent Claim
106 words
A method of killing or severely damaging unwanted plants, which comprises applying to the locus of the plants, an effectively lethal or severely damaging amount of a compound of the formula: ##STR9## wherein rings A and B are unsubstituted, or carry one or more substituents, each substituent being a lower alkyl radical; a fluorine, chlorine, bromine, or iodine atom; a lower alkoxy radical; a cyano group; a nitro group; a lower alkylcarbonyloxy radical; a methylenedioxy radical; an amino group; or a mono- or di-lower alkyl substituted amino group, and wherein Het stands for a 1,2,4-trizol-1-yl radical; or a salt of the compound of the foregoing formula.
Claim 7
Independent Claim
106 words
A method of killing or severely damaging unwanted plants, which comprises applying to the locus of the plants, an effectively lethal or severely damaging amount of a compound of the formula: ##STR9## wherein rings A and B are unsubstituted, or carry one or more substituents, each substituent being a lower alkyl radical; a fluorine, chlorine, bromine, or iodine atom; a lower alkoxy radical; a cyano group; a nitro group; a lower alkylcarbonyloxy radical; a methylenedioxy radical; an amino group; or a mono- or di-lower alkyl substituted amino group, and wherein Het stands for a 1,2,4-trizol-1-yl radical; or a salt of the compound of the foregoing formula.
Claim 8
Dependent Claim

Claim 9
Independent Claim
120 words
A method of selectively inhibiting the growth of grass weeds in broadleaved crops, which comprises applying to the locus of the crop, in an amount sufficient to inhibit the growth of grass weeds but insufficient substantially to damage the crop, a compound of the formula: ##STR10## wherein rings A and B are unsubstituted, or carry one or more substituents, each substituent being a lower alkyl radical; a fluorine, chlorine, bromine, or iodine atom; a lower alkoxy radical; a cyano group; a nitro group; a lower alkylcarbonyloxy radical; a methylenedioxy radical; an amino group; or a mono- or di-lower alkyl substituted amino group, and wherein Het stands for a 1,2,4-triazol-1-yl radical; or a salt of the compound of the foregoing formula.
Claim 10
Independent Claim
120 words
A method of selectively inhibiting the growth of grass weeds in broadleaved crops, which comprises applying to the locus of the crop, in an amount sufficient to inhibit the growth of grass weeds but insufficient substantially to damage the crop, a compound of the formula: ##STR10## wherein rings A and B are unsubstituted, or carry one or more substituents, each substituent being a lower alkyl radical; a fluorine, chlorine, bromine, or iodine atom; a lower alkoxy radical; a cyano group; a nitro group; a lower alkylcarbonyloxy radical; a methylenedioxy radical; an amino group; or a mono- or di-lower alkyl substituted amino group, and wherein Het stands for a 1,2,4-triazol-1-yl radical; or a salt of the compound of the foregoing formula.
Claim 11
Dependent Claim
118 words
