## Abstract The BF~3~ Β· Et~2~Oβ and the CH~3~SO~3~Hβcatalysed rearrangements of 10 Ξ±βvinylcyclobutanones have been examined. With little acid, the Ξ²,Ξ²βdialkyl derivatives **1** were transformed into linear dienones **2** and **3**; with more acid, they were converted into cyclopentenones **4** by _
