Official abstract text for this publication.
There is provided a novel intermediate for producing pesticides. A method for producing the compound of Formula (3) comprises reacting an aromatic ketone compound of Formula (4) and a substituted acetophenone compound of Formula (5) as starting raw materials in an organic solvent or water in the presence or absence of an additive in the presence of a base in a suspended state. A method may comprise dehydrating the compound of Formula (3). A method for producing compound (2) in one step comprises reacting compound (4) and compound (5) to obtain compound (3). Further, a method for producing an isoxazoline compound of Formula (1) comprises reacting compound (2) and a hydroxylamine in an aliphatic or an aromatic hydrocarbon solvent which is optionally substituted by a halogen atom by adding an additive selected from a phase-transfer catalyst, a C 1 -C 6 alcohol and an aprotic polar solvent in the presence of a base and water.
