FUNGICIDE MEANS AND METHOD OF MAKING THE ACTIVE SUBSTANCE

Fungicidally active novel spiro derivatives of 3-(3,5-dihalogenophenyl)-oxazolidine-2-thion-4-ones of the formula in which X and Y each independently is halogen, and n is 2 or 3, are produced by reacting an alpha -hydroxy-cycloalkylcarboxylic acid or acid ester of the formula in which R is hydrogen...

Summary:Fungicidally active novel spiro derivatives of 3-(3,5-dihalogenophenyl)-oxazolidine-2-thion-4-ones of the formula in which X and Y each independently is halogen, and n is 2 or 3, are produced by reacting an alpha -hydroxy-cycloalkylcarboxylic acid or acid ester of the formula in which R is hydrogen or alkyl with 1 to 4 carbon atoms, (a) with an isothiocyanate of the formula or (b) with an aniline of the formula in the presence of a diluent, and then cyclizing the alpha -hydroxycycloalkyl-carboxylic acid amide formed of the formula
