Esters, ketones, nitriles and nitro compounds bearing an .alpha.-nitro substituent react with certain salts of aliphatic nitro compounds with displacement of the .alpha.-nitro substituent. The resulting products are esters, ketones, nitriles and nitro compounds bearing a .beta.-nitro substituent. Very good yields of the products are obtained when the reaction is run in an aprotic solvent. The .beta.-nitro products are useful in the treatment of various plant pathogens. The method is applicable to the preparation of a variety of .beta.-nitroesters, .beta.-nitroketones, .beta.-nitronitriles and .alpha.,.beta.-dinitro compounds. Many of these .beta.-nitro compounds are novel compounds not known heretofore.
含有α-硝基取代基的酯类、酮类、腈类和硝基化合物可与某些脂肪族硝基化合物的盐反应,并取代α-硝基取代基。所得产物是含有β-硝基取代基的酯类、酮类、腈类和硝基化合物。当在无质子溶剂中进行反应时,可以获得非常好的产率。β-硝基产物在治疗各种植物病原体方面非常有用。该方法适用于制备各种β-硝基酯类、β-硝基酮类、β-硝基腈类和α,β-二硝基化合物。其中许多β-硝基化合物是迄今为止未知的新化合物。
