PROCEDURE FOR OBTAINING COMPOUNDS OF FORMULA (I), IN WHICH R1, R2, R3, R3 MAY ALREADY BE SEVERAL TYPES OF RADICALS, BY ARILATION OF OLEFINS CATALYZED BY PALADIUM CONSISTS IN THE REACTION OF A COMPOUND OF FORMULA (II) , WITH A COMPOUND OF FORMULA HA, IN WHICH X IS IODINE OR BROMINE AND THE OTHER SYMBOLS HAVE THE SAME MEANING AS IN FORMULA (I). THE REACTION IS EFFECTED IN THE PRESENCE OF AN ALKALINE OR ALKALINE EARTH OF A C1-12 ALIPHATIC MONOCARBOXYL ACID, OF BENZOIC ACID, OR OF AN AMIDE AS A SOLVENT, AND OF A PALADIUM COMPOUND, SUCH AS ARSENIOUS OR CATHOSPHORIC PHOSPHORUSES. APPLICATIONS AS OPTICAL BRIGHTENERS OR INTERMEDIATE TO PRODUCE OPTICAL BRIGHTENERS, SUCH AS SCINNERS, ADHESIVE ADDITIVES, INSECTICIDES AND ACTINIC STABILIZERS. |
