二茚基稀土氢化物在Claisen重排反应中的应用

Application of bis(indeny)rare - earth hydride in Claisen rearrangement

在温和的条件下,二茚基稀土氢化物分别与苯乙酸烯丙酯和正丁酸烯丙酯反应,得到了发生Claisen重排反应后的相应产物2-烯丙基苯乙醛和2-乙基-4-戊烯醛。

The alpha - 2 - propenyl - benzeneacetaldehyde have been prepared by the allyl - benzeneacetate with the bis( in-deny) rare - earth hydride, because of the Claisen rearrangement. The 2 - ethyl - 4 - pentenal have been prepared by the allyl - bu-tyrate with the bis(indeny)rare - earth hydride,because of the Claisen rearrangement.
