PROCEDURE FOR OBTAINING ILLUROS FROM FORMULA (I), IN WHICH R, R, R AND R MAY BE SEVERAL TYPES OF RADICALS; F IS PHOSPHORUS, ARSENIC OR ANTIMONY; M IS SULFUR OR OXYGEN; AND A IS THE CATIONIC PORTION OF THE BASE USED. CONSISTS OF THE REACTION OF A BASE WITH A SULPHONE ILURO OF FORMULA (II), IN WHICH ALL THE SYMBOLS HAVE THE SAME MEANING AS IN FORMULA (I). THE REACTION IS CARRIED OUT IN A POLAR SOLVENT, AT A TEMPERATURE BETWEEN AMBIENT AND 200 C. THESE COMPOUNDS HAVE APPLICATIONS AS CATALYST FOR THE OLIGOMERIZATION OF ETHYLENE. |
