Claim 3
Dependent Claim
89 words
A PROCESS FOR ALKYLATING THE MUCLEUS OF THIOPHENE WITH 2-PENTENE WHICH COMPRISES COMMINGLING THE THIOPHENE AND 2-PENTENE IN A RATIO OF FROM 2 TO 20 MOLECULAR PROPORTIONS OF THE FORMER PER ONE MOLECULAR PROPORTION OF THE LATTER AND SUBJECTING THE RESULTANT MIXTURE TO REACTION AT A TEMPERATURE OF ABOUT 30*-60*C. AND A PRESSURE OF FROM ABOUT ATMOSPHERIC TO ABOUT 100 ATMOSPHERES IN THE PRESENCE OF A PREFORMED COMPLEX OF BORON TRIFLUORIDE AND A METAL FLUORIDE IN WHICH THE METAL IS SELECTED FROM THE GROUP CONSISTING OF MANGANESE AND CHROMIUM.
