摘要： 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.
