Abstract: Imidazolyl oxime ethers (I) are disclosed which contain an aromatic or heteroaromatic grouping linked to the carbon atom of the oxime ether, the oxime being etherified by a variety of groups; aliphatic, aromatic, heteroaromatic, cycloaliphatic and aliphatic substituted by aromatic, heteroaromatic or cycloaliphatic groups. The compounds are obtained from the corresponding ketones by reaction with O-substituted hydroxylamines or by reaction of metal oximates with halides of the required etherifying group. The said products (I) possess antimycotic and bactericidal activity.
