THE SILA-PUMMERER REARRANGEMENT OF 1-ALKYL-3-PHENYLSULFINYL-3-TRIMETHYLSILYLCYCLOBUTANOLS. A NEW METHOD FOR THE PREPARATION OF 3-ALKYL-2-CYCLOBUTENONES

3-Alkyl-2-cyclobutenones were produced by the sila-Pummerer rearrangement of 1-acetoxy-1-alkyl-3-phenylsulfinyl-3-trimethylsilylcyclobutanes followed by hydrolysis. β-Phenylthio-α,β- and β,γ-unsaturated ketones were major products when the corresponding cyclobutanols were employed.
