Process for producing pyrethrolone and its intermediate compound |
| abstract |
Pyrethrolone of the formula [II],n n is produced by reacting a cyclopentenolone derivative of the formula [I],n n with zinc in an aqueous alcohol solvent. And the cyclopentenolone derivative of the formula [I] is produced by reacting a propargylcyclopentenolone derivative of the formula [III],n n with vinyl halide in the presence of a palladium catalyst, a copper catalyst and a tertiary amine. These processes permit easy production of pyrethrolone of the formula [II] and an intermediate compound of the formula [I] for the production of the pyrethrolone. |
