Patent ID: 6844089

Claim:
A compound having formula VII: wherein B is an unsaturated carbocyclic 4-8 member ring, wherein if B is a 6-8-member ring, the ring optionally includes two C-atoms that form a bridge with each other, radicals R are one or more substituents, which can be the same or different and are hydrogen or a straight-chain or branched C 1 -C 6 -alkyl group: R 1 , R 2 , and R 9 are the same or different and are hydrogen, halogen, or straight-chain or branched C 1 -C 6 -alkyl groups; R 3 is hydrogen, a straight-chain or branched C 3 -C 6 -alkyl group, —OR 16 , —COOR 16 , N,N-dialkylamino, acetylamino, or halogen, wherein R 16 is hydrogen or a straight-chain or branched C 1 -C 6 -alkyl group; R 8 is halogen; R 17 and R 18 are the same or different and are hydrogen, halogen, or a straight-chain or branched C 1 -C 6 -alkyl group; R 19 and R 20 are the same or different and are hydrogen or a straight-chain or branched C 1 -C 6 -alkyl group; or at least one of the substituent pairs R 17 /R 19 and R 18 R 20 link together to form an alicyclic ring; or the substituent pair R 19 /R 20 link together to form a heterocyclic ring together with the nitrogen atom; and A 1 and A 2 are the same or different and are cyano, nitro, or —COOR 16 , wherein R 16 is hydrogen or a straight-chain or branched C 1 -C 6 -alkyl group.
