[摘要]：Reaction of alkyl, acetoxy, and silyl enol ethers of 3-(organosilyl)cyclohexanone with mol. dioxygen in toluene at 110? produced the corresponding conjugated enones in yields up to 88% yield. The reaction of the same type failed on replacement of the silyl group at the C-3 position with an iso-Pr group. These results indicate the existence of an unprecedented Si-induced ene-type reaction. Its reaction mechanism, generality, limitations, and exceptions are discussed.
