[0166] As mentioned above, substituents such as R 1 It may be, inter alia, an 8-, 9- or 10-membered heteroaromatic bicyclic ring system optionally substituted with up to 5 substituents selected from the substituents as 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 5 substituents include 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 (eg for R 1 ), and r is an integer from 0 to 5, limited by the number of positions available on each H group.

[0170] Although R is shown in structures U-1 to U-61 and H-1 to H23 v groups, but note that they do not have to be present as they are optional substituents. Nitrogen atoms that need to be substituted to fill their valences can be replaced by H or R v replace. Note that when (R v ) r When the point of attachment to the U or H group is shown floating, (R v ) r Can be attached to any available carbon or nitrogen atom in the U or H group. Note that when the point of attachment on a U or H group is shown as floating, then said U or H group can be attached to the formula via any available carbon or nitrogen in the U or H group by replacing a hydrogen atom 1 on the rest. It should be noted that some U groups can only be replaced by less than 2 R v Group substitution (eg, 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, EC(=X1); a is 1, 2 or 3; and R1, R2, R3, R4, R5a, R5b, R6, R7, 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

field of invention [0001] The present invention relates to certain pyrimidines suitable for agronomic, non-agronomic and animal health uses Compounds, N-oxides thereof, salts thereof and combinations thereof, methods of using them in agronomic and non-agronomic settings to control invertebrate pests such as arthropods, and in general to treat animal parasitic infestations or method of infection. Background of the invention [0002] Control of invertebrate pests is extremely important for high crop efficiency. Damage to crop growth and storage by invertebrate pests can result in significantly lower yields, resulting in higher costs for consumers. Control of invertebrate pests is also important for forestry, greenhouse crops, ornamental plants, nursery crops, stored food and fiber products, livestock, homes, turf, wood products, and public sanitation. There are many products commercially available for this purpose, but there is a continuing need for new compounds that are ...
