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.
3-烷基-2-环丁烯酮是通过 1-乙酰氧基-1-烷基-3-苯基亚磺酰基-3-三甲基甲硅烷基环丁烷的 sila-Pummerer 重排然后水解产生的。当使用相应的环丁醇时,β-苯硫基-α,β-和β,γ-不饱和酮是主要产物。
