IMPROVEMENT IN/OR RELATING TO SYNTHESIS OF O- ALKYL DERIVATIVES OF OXIME ETHERS OF PIPERONAL AS POTENTIAL FUNGICIDES

摘要

The present invention relates to the preparation O- alkyl oxime ether derivatives of piperonal wherein piperonal oxime reacts with alkyl halides in presence of a base in an organic solvent with continuous refluxing at 30 - 50°C to produce alkylated products. It also involves various solid and liquid preparations obtained by incorporating O-alkyl oxime ether derivatives of piperonal either alone or in combination with one or more suitable carriers, adjuvant and/or diluents for use in preventing or at least inhibiting the growth of fungi.
