PROCEDURE FOR OBTAINING DIPHENYLAMINES FROM FORMULA (I), IN WHICH R IS METHYL, ETHYL OR N-PROPYL AND R MAY BE ONE OF SEVERAL TYPES OF RADICALS. IT CONSISTS OF THE ALKYLATION REACTION OF A COMPOUND OF FORMULA (II), IN WHICH R HAS THE SAME MEANING AS IN FORMULA (I). THE REACTION IS CARRIED OUT BY GENERATING THE ANION WITH A WEAK BASE, WHICH IS RENTED WITH AN ALKYLATING AGENT SUCH AS DIALKYL SULPHATE, IN AN INERT SOLVENT, AT A TEMPERATURE BETWEEN 20 <025> C AND 120 <025> C. THESE COMPOUNDS HAVE APPLICATIONS IN AGRICULTURE FOR THE CONTROL OF INSECTS, ARACHNIDS AND ECTOPARASITES. |
