Preparation and molecular structure of (3-acetyl-4,5-dihydrofuran-2-yl)tetracarbonylmanganese(I)

Abstract
Treatment of cis-(2-oxacyclopentylidene)nonacarbonyldimanganese with butyl-lithium followed by acetyl chloride gives (3-acetyl-4,5-dihydrofuran-2-yl)-tetracarbonylmanganese whose molecular structure was determined by X-ray crystallography.
