通过金(I)催化烯基乙烯基醚的Claisen重排合成取代的1,3-二烯。n -杂环碳金氯化催化剂(IPrAuCl)具有良好的活性和选择性,产率高。阳离子-π相互作用对反应速率有重要影响。
Synthesis of substituted 1,3-dienes was achieved via gold(I)-catalyzed Claisen rearrangement of allenyl vinyl ethers. The N-heterocyclic carbene gold chloride catalyst (IPrAuCl) was superior in terms of activity and selectivity and afforded the 3,3-product in excellent yields. A proposed cation-π inter-action played a significant role in affecting the reaction rate.
