Patent ID: 7652144

Claim:
A compound of formula XIX wherein R 1 is C 1-4 alkyl optionally substituted by one or more of halo, cycloalkyl or cycloalkenyl; R 2 is alkyl, alkenyl or alkynyl each optionally substituted by one or more of halo, cycloalkyl or cycloalkenyl; or cycloalkyl or cycloalkenyl each optionally substituted by one or more of halo, methylidene or alkyl; or optionally substituted cyclothioalkyl consisting of a non-aromatic monocyclic or multicyclic ring system of 3 to about 10 ring atoms wherein at least one of the ring atoms is sulfur and the other ring atoms are carbon and the substituted cyclothioalkyl is substituted by one or more halo, or any ring sulfur atom is optionally oxidized to the corresponding S-oxide or S,S-dioxide; or optionally substituted cyclothioalkenyl consisting of a non-aromatic monocyclic or multicyclic ring system of 3 to about 10 ring atoms wherein at least one of the ring atoms is sulfur, the other ring atoms are carbon and the ring system contains a carbon-carbon double bond and the substituted cyclothioalkenyl is substituted by one or more halo or any ring sulfur atoms is optionally oxidized to the corresponding S-oxide or S,S-dioxide; Q 1 , Q 2 and Q 3 are independently nitrogen, CX or CH, provided that at least one of Q 1 , Q 2 and Q 3 is other than CH; Z 1 and Z 2 are independently oxygen or sulfur; and X is halo; provided that Z 1 amd Z 2 are not both sulfur.
