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.
本发明涉及一般式(I)的硝基醇衍生物,其中R1是C2-12烯丙基或烷二烯基,具有一个或多个C1-3烷基取代基的C4-12烷氧基烷基或烷氧基烯基,C3-6环烷基或环烯基,呋喃基,硝基呋喃基或苯基,其中选自羟基,C1-4烷氧基,卤素,硝基,C1-4烷二氧基和C1-4烯酰氧基基团的相同或不同的取代基,R2和R4分别表示氢或它们共同形成一个价键,R3是C1-12烷酰氧基,具有一个或多个卤素取代基或氢原子的苯甲酰氧基,R5是C1-12烷基或苯基,具有一个或多个卤素取代基,但如果R2和R4均表示氢,则R1不是未取代的苯基且R3仅可以表示C1-4烷酰氧基或具有一个或多个卤素取代基的苯甲酰氧基,并且如果R2和R4共同形成一个价键且R5为甲基,则R1不是未取代的苯基。上述定义的硝基烯醇衍生物以及已知的1-苯基-2-硝基-3-乙酰氧基-丙烷-1具有有价值的杀虫效果,主要是杀真菌活性,可优化地应用于农业作为植物保护剂。
