## Abstract The intramolecular iron‐catalyzed ring expansion reaction of epoxyalkenes was investigated with a preformed iron(salen) [Fe(Salen)] complex. The formal insertion of the alkene into the epoxide generated hexahydrocyclopenta[__c__]furan derivatives in moderate to good yields and diastereo

## Abstract A considerable improvement is reported in the iron‐catalyzed ring‐expansion reactions of epoxides generating tetrahydrofuran derivatives by formal insertion of an alkene. Optimization of the catalyst system revealed that a preformed [Fe(salen)] complex minimizes the formation of polymer
