Préparation de cyclobutanones substituées par l'intermédiaire de dérivés sulfurés

Substituted cyclobutanones have been obtained from the corresponding 1,3‐diones by converting one oxo group in the latter compounds into sulfur containing group(s) and subsequently removing the S group(s) with Raney‐Nickel. The mass spectral fragmentation patterns of these compounds are discussed.
