Abstract: 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.

Abstract: DISCLOSED IS A PROCESS FOR NITROSATING NITROSATABLE PHENOLIC MATERIAL. NITROGEN TRIOXIDE AND THE PHENOLIC MATERIAL ARE INTRODUCED SIMULTANEOUSLY AT SPECIFIC RATES INTO AN AGITATED, ACIDIC, AQUEOUS MEDIUM ESTABLIXHED AND MAINTAINED IN THE TEMPERATURE RANGE FROM ABOUT -20 TO ABOUT 20* C., AND HAVING AN INITIAL CONCENTRATION OF NITROUS ACID IN A RANGE FROM ANOUT 0 TO ABOUT 1% BY WEIGHT OF THE AQUEOUS MEDIUM. THE INITIAL PH OF THE AQUEOUS MEDIUM IS LESS THAN ABOUT 5, PREFERABLY ABOUT 1, AND COMPRISES WATER AND, DISSOLVED IN THE WATER, ACID MATERIAL SELECTED FROM THE GROUP CONSISTING OF WATER-SOLUBLE STRONG ACIDS LIKE NITRIC ACID AND SULFURIC ACID. THE RATE OF INTRODUCTION OF THE PHENOLIC MATERIAL INTO THE AQUEOUS MEDIUM IS PREFERABLY SUBSTANTIALLY THE RATE AT WHICH THE PHENOLIC MATERIAL IS NITROSATED IN THE AQUEOUS MEDIUM. THE RATE OF INTRODUCTION OF NITROGEN TRIOXIDE INTO THE AQUEOUS MEDIUM IS SUBSTANTIALLY AT THE RATE AT WHICH A SLIGHT STOICHIOMETRIC EXCESS, RELATIVE TO THE PHENOLIC MATERIAL BEING INTRODUCED INTO THE AQUEOUS MEDIUM OF NITROUS ACID IS ESTABLISHED AND MAINTAINED IN THE REACTION MEDIUM. AS REACTION TAKES PLACE NITROSATED PHENOLIC PRODUCT FORMS AND PRECIPITATES. PREFERABLY THE REACTION MIXTURE THAT RESULTS IS MAINTAINED WITH AGITATION IN THE TEMPERATURE RANGE UNTIL THE REACTION IS SUBSTANTIALLY COMPLETE, AND THEN THE PRECIPITATED NITROSATED PHENOLIC PRODUCT IS SEPARATED FROM THE REACTION MIXTURE.

Abstract: The invention provides an oxidation process for converting 4nitroso-m-cresol to the corresponding 4-nitro-m-cresol by reacting the nitroso compound with an oxidizing agent in the presence of a catalyst at reflux temperatures in a reaction solvent solution including lower aliphatic and alicyclic ketones. The mixture thereafter is cooled and the 4-nitro-m-cresol is recovered from the solvent solution.
