Abstract

Benzoylurea derivatives, novel compounds with the general chemical formula #, where X and Y both represent hydrogen or halogen atoms, with the condition that both X and Y cannot simultaneously be hydrogen atoms; A and B both represent low-weight alkyl hydrogen atoms or halogen atoms, with the condition that both A and B cannot simultaneously be hydrogen atoms; and R represents an alkyl group with a fluorine substituent containing one or two carbon atoms, which can be used as an insecticide. The following are novel intermediate compounds used in the synthesis of these substances.

Claims (10)

1. Benzoylurea derivatives, a novel compound with the general chemical formula #, where X and Y both represent hydrogen or halogen atoms, with the condition that both X and Y cannot simultaneously be hydrogen atoms; A and B both represent low-weight alkyl hydrogen atoms or halogen atoms, with the condition that both A and B cannot simultaneously be hydrogen atoms; and R represents an alkyl group with a fluorine substituent containing 1 or 2 carbon atoms. 2. A compound as described in claim 1, where X is a halogen atom and Y is a hydrogen atom, or where X and Y are the same or different halogen atoms. 3. A compound as described in claim 1 or 2, where A is a halogen atom and B is a hydrogen atom, or where A and B are the same or different halogen atoms. 4. Various derivatives of benzoylurea with 4 chemical formulas and (chemical formula...). 5. Procedure for preparing benzoylurea derivatives that are novel compounds with a general formula (I) (chemical formula), where X and Y both represent hydrogen or halogen atoms, provided that both X and Y are not hydrogen atoms simultaneously; A and B both represent low-weight alkyl hydrogen atoms or halogen atoms, provided that both A and B are not hydrogen atoms simultaneously; and R represents an alkyl group with a fluorine substituent containing 1 or 2 carbon atoms. The procedure consists of: i) reacting a compound with a general formula (chemical formula) where A, B, and R have the meanings defined above with a compound with a general formula (III) (chemical formula) where X and Y have the meanings defined above; or ii) reacting a compound with a general formula (IV) (chemical formula) where X and Y have the meanings defined above with a compound with a general formula (V) (chemical formula) where A, B, and R have the meanings defined above. 6. Methods of insect control consisting of applying any one of the compounds listed in claims 1 through 4 in an effective insecticidal quantity directly onto the insects or into their habitats. 7. An insecticide mixture containing any one of the active ingredients that is a benzoylurea derivative, as described in claims 1 through 4. 8. A novel derivative of aniline with a general formula (chemical formula), where A and B both represent hydrogen atoms, low molecular weight alkyl groups, or halogen atoms, provided that A and B cannot both be hydrogen atoms simultaneously, and R represents an alkyl group with a fluorine substituent containing 1 or 2 carbon atoms. 9. A procedure for preparing a new aniline derivative with the general formula (II) (chemical formula), where A and B both refer to low-weight alkyl hydrogen atoms or halogen atoms, provided that A and B are not both hydrogen atoms, and B refers to an alkyl group with a fluorine substituent containing 1 or 2 carbon atoms. The procedure involves reacting a compound with the general formula (VI) (chemical formula), where A and B have the meanings defined above, with a compound with the general formula (VII) (chemical formula), where R has the meanings defined above, and M refers to a low-weight alkyl group or aryl group, in the presence of a base. 10. The process as described in claim 9, using a polar aprotic solvent or using a tertiary alcohol as the solvent for the reaction. (10 claims, drawing - picture)
