Azole derivatives of the formula I <IMAGE> where A equals CH or N and R<1>/R<2> equals substituted or unsubstituted phenyl, biphenylyl, phenoxyphenyl, benzylphenyl, benzyloxyphenyl, naphthyl, thienyl, furyl or pyridyl and their salts and esters have outstanding antimycotic and fungicidal activity in all stereoisomeric forms. They are obtained by reaction of a compound II <IMAGE> with a sulphur ylide of the formula III <IMAGE> to give the compound IV <IMAGE> which is reacted with the corresponding compound V <IMAGE> to give I. Compound VI <IMAGE> can also be used as a starting material and is reacted with 2 equivalents of IIIa <IMAGE> compound IV being formed; or compound VI is first reacted with an equivalent of IIIa to give II, and II is then reacted, without working up, with the sulphur ylide IIIb (CH3)2SCH2 to give IV and this is reacted with V to give I. |
