    • A process for the manufacture of imidazolylvinyl ethers of the formula ##STR1## wherein Im represents the substituted or unsubstituted 1-H-imidazol-1-yl group and An, R and Y are defined hereinbelow by condensation of a corresponding ketone of the formulaAr--CO--CHR--Im (II)with the splitting-off of a Z group, with a condensable substance of the formulaZ--Y (III)in the aqueous solution of a strong inorganic base, preferably in concentrated aqueous soda lye. The reaction may also be carried out in the presence of a second liquid organic phase, preferably benzene or toluene, especially in the presence of a phase transfer catalyst in this case. Through careful crystallization of the product manufactured according to this method, it is possible to manufacture approximately pure E-isomers of the imidazolylvinyl ether of formula (I), without the requirement of chromatographic separation.

    • Aryl-imidazol-1-yl vinyl ethers and their acid addition salts are disclosed, wherein the imidazolyl vinyl ether has the formula: ##STR1## Ar in the formula represents a substituted or unsubstituted aryl or heterocyclic radical; R represents hydrogen or a C.sub.1 -C.sub.12 alkyl or cycloalkyl (saturated or unsaturated) or Ar as above; Im represents a 1-H-imidazol-1-yl group (unsubstituted or substituted); and Y represents a saturated or unsaturated C.sub.1 -C.sub.12 alkyl or a group --Z--Ar in which Ar has the above meaning and --Z-- is a saturated or unsaturated C.sub.1 -C.sub.12 alkylene wherein each of the alkyl and the alkylene may have a carbon chain once or twice interrupted by or, in the case of the alkylene, terminated on its Ar-end by oxy, thio, sulfinyl or sulfonyl bridges, always with the proviso that at least one of Ar and Y is a heterocyclic radical. These compounds are wide-spectrum fungicides and bactericides, and the preferred compounds among them are hydrophilic.
