ISOMERIZATION OF EPOXYALKENES TO 2,5-DIHYDROFURANS AND CATALYST COMPOSITIONS USEFUL THEREFOR

摘要

DISCLOSED ARE PROCESSES FOR THE ISOMERIZATION OF EPOXYALKENES TO HYDROFURANS BY CONTACTING AN EPOXYALKENE WITH A CATALYST COMPRISING A QUATERNARY ORGANIC ONIUM IODIDE COMPOUNDS, OPTIONALLY DEPOSITED ON A NON-ACIDIC SUPPORT AND/OR IN COMBINATION WITH A LEWIS ACID CO-CATALYST. THE CATALYST MAY COMPRISE A SUPPORTED CATALYST, AN UNSUPPORTED CATALYST OR A SOLUTION OF THE CATALYTICALLY- ACTIVE COMPONENTS IN AN INERT, ORGANIC SOLVENT.
