The present invention relates to new fluorinated cyclohexane derivatives of the formula ##STR1## in which the symbols used have the meaning indicated in the description, a process for their preparation, intermediates of the formula ##STR2## in which the symbols have the meaning indicated in the description, and the use of the new fluorinated cyclohexane derivatives as fungicides and intermediates.
Sulfur tetrafluoride converts aliphatic nitro acids to the corresponding trifluoromethyl compounds. The yield is poor with primary nitro acids; but high yields of fluoronitrocarbons, otherwise difficult to obtain, are produced from certain γ-substituted butyric acids and from substituted acrylic acids. Eleven new fluoronitrocarbons are described.
The new N-substituted .alpha.-fluoroalkyl-lactams of the general formula ##STR1## in which the substituents and indices have the meaning indicated in the description, exhibit a strong action against pests and can be employed in particular for combating unwanted fungi.
