    Abstract: Preparation of E7/Z9-alkadien-1-ols of the formula I (where R = C1-C8-alkyl, R = H or a base-stable hydroxyl protecting group) by reacting an optionally OH-protected 7-hydroxyheptanal II OHC-(CH2)6-OR II with a phosphorus ylide III in which R and R denote a low-molecular weight alkyl group or are connected to one another to give an optionally C1-C4-alkyl-substituted dioxane or dioxolane system and R stands for alkyl, cycloalkyl or optionally substituted phenyl, in a Wittig reaction to give compounds of the formula IV which are converted by the action of acid into the trans 2-nonenal V which is reacted by means of a further Wittig reaction with a phosphorus ylide VI in which R and R have the abovementioned meaning, to give the E7/Z9-alkadienols which are obtained from the reaction mixture in a manner known per se.

    Abstract: where R1 is hydrogen, alkyl or halogen, R2 and R3 are hydrogen or alkyl, R4 is hydrogen, alkyl, alkenyl, alkynyl, haloalkyl, haloalkenyl, unsubstituted or substituted aralkyl, COR5, CO2R6 or CONR7R8, R5 and R6 are alkyl, unsubstituted or substituted aryl or unsubstituted or substituted aralkyl, R7 and R8 are hydrogen, alkyl, unsubstituted or substituted aryl or unsubstituted or substituted aralkyl and n is 0, 1, 2 or 3, and its plant-tolerated acid addition salts, excluding the compounds where, simultaneously, R4 is hydrogen, acetyl or propionyl, n is 0 or 1 and R1, R2 and R3 are hydrogen, and fungicides containing the novel piperidines and salts.
