A process for the preparation of ligand for use in the preparation of molluscicidal chelate

摘要

The use as a molluscicide of a chelate of aluminium (III) with a ligand of formula I or of iron (III) with a ligand of formula II I: [R<1>COCHCOCR<2>]<-> II: [R<3>NO.N=O]<-> in which formulae: R<1> and R<2>, which may be identical or different, represent: methyl, ethyl, propyl, methoxyethyl, ethoxyethyl, dimethoxy methyl or diethoxymethyl and R<3> represents: C1-C6 alkyl, provided that when the alkyl group contains more than four carbon atoms the group is a branched chain alkyl group.
