Synthesis of Five-Membered Cyclic Ketones Using Potassium Tetracarbonylferrate(2—)

Abstract
Various five-membered cyclic ketones were prepared from 1,4-dihaloalkanes and potassium tetracarbonylferrate(2—) in moderate to high yields. However, the yields of six- or seven-membered cyclic ketones from the corresponding dihalides were rather low.
