 note = {The reaction of chromous acetate with many kinds of 5α- and 5β-dihaloketo-steroids, which possess an oxo group on each position in ring A and B, was investigated. gem-Dihaloketones were reduced rapidly with chromous acetate in acetic acid-chlorofrm solution to give corresponding monohaloketones, accompanyed further reduced products, parent ketones. a, a' -Dihaloketones were also dehalogenated reductively to monohaloketones and small amount of parent ketones. The relative yields of reduced products varyed with the structure of dihaloketones and slightly on the mode of reaction. Several new products were also obtained. The reactivity of dihaloketones toward chromous acetate decreased in the following order: gem-dihaloketones ＞ a, a' -dihaloketones, axial-halogen ＞ equatorial-halogen, and bromides ＞ chlorides., 紀要論文},
