Conversion of 2,5-dihydrothiophene 1,1-dioxides into highly functionalized (η4-buta-1,3-diene)tricarbonyliron(0) complexes
Abstract
Treatment of functionalized 2,5-dihydrothiophene 1,1-dioxides with nonacarbonyldi-iron in refluxing toluene affords functionalized (η4-buta-1,3-diene)tricarbonyliron(0) complexes.
