| Abstract: | The silica-supported iron Lewis acid [(η5-C5H5)Fe(CO)2(THF)]+ [BF4]+ (1), was found to catalyze the formation of an enol ester, cyclopropane, or aziridine from a diazo compound and an aldehyde, olefin, or imine, respectively. Unlike the non silica-supported iron Lewis acid, the catalyst is recoverable and reusable. |
