Abstract: Cyclohexene derivatives of the formula I I where R1 and R2 are hydrogen or tert.-butyl and N and X are members of a heterocyclic ring in which X is an alkylene chain of four, five or six members, one of which may be a hetero-atom, such as oxygen, and where the alkylene radicals are unsubstituted or substituted by alkyl or by -CH2OH or its acetyl or propionyl derivative, and their salts are used in fungicides.

Abstract: A process for the preparation of the sought-after scent 2,5-dimethyl-4-hydroxy-2,3-dihydrofuran-3-one, and novel intermediates for the preparation of this compound. 2,5-Dimethyl-4-hydroxy-2,3-dihydrofuran-3-one is prepared by first epoxidizing hex-3-ene-2,5-diol in the liquid phase with hydrogen peroxide to give the novel compound 3,4-epoxy-hexane-2,5-diol, which at 40 DEG -280 DEG C. is converted, by means of a catalytic amount of an acid, to the novel compound 2,5-dimethyl-3,4-dihydroxy-tetrahydro-furan. The latter is dehydrogenated by means of oxygen over a silver catalyst or copper catalyst to give the nove compound 2,5-dimethyl-4-hydroxy-tetrahydrofuran-3-one, which is oxidized by means of bismuth oxide, in concentrated acetic acid solution, to give the desired compound 2,5-dimethyl-4-hydroxy-2,3-dihydrofuran-3-one.

Abstract: Prodn. of ketones of formula R1COR2 (I) (where R1 is 1-17C alkyl or 7-12C aralkyl; R2 is as R1 or 5-8C cycloalkyl or aryl) comprises gas-phase decarboxylation under dehydrating conditions of R1COOH or its mixt. with R5COOH. Reaction is carried out over a new catalyst contg. 5-30 wt. % ZrO2 and/or ThO2 with the balance being anatase. (I) are useful as solvents and intermediates for dyes, plant protection agents and pharmaceuticals.
