Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 200 words
A compound of the formula: ##STR10## wherein A is a chloro, bromo, fluoro, iodo, trifluoromethyl, trifluoromethoxy, fluorosulfonyl, methyl, ethyl, phenyl, methoxy, chloromethyl, (C 1 -C 2 )alkoxycarbonyl, cyano or hydroxy group; A 1 and B are each independently selected from the group consisting of hydrogen, chloro, bromo, fluoro and methyl group; X is cyano, thiocyano, isothiocyano, methylsulfonyloxy, thio(C 1 -C 2 )alkyl, (C 1 -C 2 )alkoxy, carbamoyloxy (--OC(O)NR 3 ), thiocarbamoylthio (--SC(S)NR 3 ), azide, (C 1 -C 4 )alkylcarbonyloxy, phenylcarbonyloxy, phenoxy, phenylthio, trifluoromethylcarboxy, imidazolyl or triazolyl group; and when X is a phenylcarbonyloxy, a phenoxy or phenylthio substituent, the phenyl moiety may be independently substituted with one substituent selected from the group consisting of chloro, fluoro, bromo, iodo or methyl group; Y and Z are each independently a hydrogen, cyano, thiocyano, isothiocyano, methylsulfonyloxy, thio(C 1 -C 2 )alkyl, (C 1 -C 2 )alkoxy, carbamoyloxy (--OC(O)NR 3 ), azide or (C 1 -C 4 )alkylcarbonyloxy group and either Y or Z may be an imidazolyl or triazolyl group; R 1 and R 2 are each independently a (C 1 -C 6 )alkyl group; and each R 3 is independently a hydrogen or a (C 1 -C 4 )alkyl group.

Claim 3
Dependent Claim 186 words
The compound of claim 1 wherein A is a chloro, bromo, fluoro, trifluoromethyl, fluorosulfonyl, methyl, ethyl or methoxy group, A 1 and B are each independently selected from the group consisting of hydrogen, chloro, bromo, fluoro and methyl group; X is cyano, thiocyano, isothiocyano, methylsulfonyloxy, thio(C 1 -C 2 )alkyl, (C 1 -C 2 )alkoxy, carbamoyloxy (--OC(O)NR 3 ), thiocarbamoylthio (--SC(S)NR 3 ), azide, (C 1 -C 4 )alkylcarbonyloxy, phenylcarbonyloxy, phenoxy, thiophenyl, imidazolyl or triazolyl group; and when X is a phenylcarbonyloxy, a phenoxy or thiophenyl substituent, the phenyl moiety may be substituted with one substituent selected from the group consisting of chloro, fluoro, bromo, iodo or methyl group; Y and Z are each independently a hydrogen, cyano, thiocyano, isothiocyano, methylsulfonyloxy, thio(C 1 -C 2 )alkyl, (C 1 -C 2 )alkoxy, carbamoyloxy (--OC(O)NR 3 ), azide, or (C 1 -C 4 )alkylcarbonyloxy group and either Y or Z may be an imidazolyl or triazolyl group; R 1 and R 2 are each independently a (C 1 -C 4 )alkyl group; and each R 3 is independently a hydrogen or a (C 1 -C 4 )alkyl group.
Claim 4
Dependent Claim 82 words
