ドデカカルボニル三鉄を用いる合成反応

抄録

Synthetic applications of triiron dodecacarbonyl, Fe₃ (CO)₁₂, are described together with its preparation and properties. Treatment of olefinic compounds with Fe₃ (CO)₃ can lead to the isomerization of a particular double bond and other synthetically useful transformations through the formation of tricarbonyliron complexes. α, β-Unsaturated ketones and imines undergo various types of cyclodimerizations through the formation of heterodiene tricarbonyliron complexes upon treatment with Fe₃ (CO)₃. These cyclodimerizations afford four-, five -, and six-membered ring systems, depending on the structure of enones and imines. Polynuclear anionic carbonyliron complexes derived from Fe₃ (CO)₁₂ effectively reduce nitro, imino and aldehyde groups.
