Abstract

The invention relates to nitroalkanol derivatives of the general formula (I), ##STR1## wherein R.sub.1 is a C.sub.2-12 alkenyl or alkadienyl group, a C.sub.4-12 alkoxyalkyl or alkoxyalkenyl group having one or more C.sub.1-3 alkyl substituents, a C.sub.3-6 cycloalkyl or cycloalkenyl group, a furyl group, a nitrofuryl group, or a phenyl group having optionally one or more identical or different substituents selected from the group consisting of hydroxy, C.sub.1-4 alkoxy, halogen, nitro, C.sub.1-4 alkylenedioxy and C.sub.1-4 alkenoyloxy groups, R.sub.2 and R.sub.4 each represent hydrogen or they form together a valence bond, R.sub.3 is a C.sub.1-12 alkanoyloxy group, a benzoyloxy group having optionally one or more halogen substituents or hydrogen atom, and R.sub.5 is a C.sub.1-12 alkyl group or a phenyl group having optionally one or more halogen substituents, with the proviso that if R.sub.2 and R.sub.4 each stand for hydrogen, R.sub.1 is other than unsubstituted phenyl and R.sub.3 may represent only a C.sub.1-4 alkanoyloxy group or a benzoyloxy group having optionally one or more halogen substituents, and with the further proviso that if R.sub.2 and R.sub.4 form together a valence bond and R.sub.5 is methyl, R.sub.1 is other than unsubstituted phenyl. The nitroalkenol derivatives defined above as well as the known 1-phenyl-2-nitro-3-acetoxy-propane-1 possess valuable pesticidal effects, primarily fungicidal activities, and can be applied to advantage in the agriculture as plant protecting agents.
