[0106] As mentioned above, substituents such as R 1 May be (among other things) an 8-membered, 9-membered, or 10-membered heteroaromatic bicyclic ring system optionally substituted with up to 3 substituents selected from the substituents defined in the Summary of the Invention . Examples of 8-membered, 9-membered, or 10-membered heteroaromatic bicyclic ring systems optionally substituted with up to 3 substituents include the ring systems H-1 to H-23 shown in Example 2, wherein R v Is any substituent as defined in the Summary of the Invention (e.g. for R 1 ), and r is an integer from 0 to 3, which is limited by the number of positions available on each H group.

[0110] Although R is shown in structures U-1 to U-61 and H-1 to H-23 v Groups, but note that since they are optional substituents, they do not have to be present. The nitrogen atom that needs to be substituted to fill its valence can be H or R v replace. Note that when (R v ) r When the connection point with U or H group is shown as floating, (R v ) r It can be attached to any available carbon or nitrogen atom in the U or H group. Note that when the point of attachment on the U or H group is expressed as floating, then the U or H group can be connected to the formula through any available carbon or nitrogen in the U or H group by replacing a hydrogen atom The rest of 1 is on. It should be noted that some U groups can only be replaced by less than 2 R v Group substitution (e.g. U-2 to U-5, U-7 to U-48, and U-52 to U-61).

Abstract

Disclosed are compounds of Formula (1), N-oxides, and salts thereof, wherein X is O or S; Y is O or S; Z is a direct bond, O, S(O)n, NR6, C(R7)2O, OC(R7)2, C(=X1), C(=X1)E, EC(=X1), C(=NOR8) or C(=NN(R6)2); a is 0, 1, 2 or 3; and R1, R2, R3, R4, R5a, R5b, R6, R7, R8, X1 and E are as defined in the disclosure. Also disclosed are compositions containing the compounds of Formula (1) and methods for controlling an invertebrate pest comprising contacting the invertebrate pest or its environment with a biologically effective amount of a compound or a composition of the invention.

Description

Invention field [0001] The present invention relates to certain pyrimidines suitable for agricultural, non-agricultural and animal health purposes Compounds, their N-oxides, their salts, and their compositions, methods of using them to control invertebrate pests such as arthropods in agronomic and non-agronomic environments, and using them in general environments to treat animal parasitic infections or Method of infection. Background of the invention [0002] In order to obtain high crop efficiency, the control of invertebrate pests is extremely important. The damage caused by invertebrate pests to the growth and storage of crops will result in a significant reduction in yield, which will result in increased consumer costs. For forestry, greenhouse crops, ornamental plants, nursery crops, stored food and fiber products, livestock, homes, turf, wood products, and public health, the prevention and control of invertebrate pests is also important. For this purpose, many products a...
