摘要：
A substituted triazolylmethyl-oxirane of the formula ##STR1## in which R is optionally substituted alkyl, aryl or cycloalkyl is prepared by reacting a triazolyl-ketone of the formula ##STR2## with (a) dimethyloxosulphonium methylide of the formula ##STR3## or (b) trimethylsulphonium methylsulphate of the formula[(CH.sub.3).sub.3 S].sup..sym. CH.sub.3 SO.sub.4.sup..crclbar.in the presence of a diluent.The end product can then be reacted with a phenol of the formulaR"--OHto produce known fungicidally active compounds of the formula ##STR4## in which R" is optionally substituted phenyl.
