Abstract

.alpha.-Aryl-.beta.-imidazol-1-yl vinyl ethers and their acid addition salts are disclosed, wherein the imidazolyl vinyl ether has the formula: ##STR1## Ar represents a substituted or unsubstituted aryl group, R an alkyl, aryl or aralkyl group, X an oxygen atom, a sulfur atom, a sulfinyl or a sulfonyl group and R1 a lower alkyl group or a nitro group. These compounds are effective wide spectrum fungicides and bactericides. To prepare these vinyl ethers, a corresponding 1-arylacylimidazole is o-alkylated in presence of NaH with a corresponding .alpha.-halogen ether, .alpha.-halogen thioether, .alpha.-halogen sulfinyl compound or a corresponding .alpha.-halogen sulfonyl compound.
