Treatment of allenyne-1,6-diols with gold and silver catalysts selectively produced 2,5-dihydrofuran and furan derivatives, respectively, in good to excellent yields through the selective activation and differentiation of the double and triple bonds in allenyne-1,6-diols. It is noteworthy that the chemoselectivity is clearly switched by simply changing the metal from gold to silver.
通过金和银催化剂分别处理有选择性的活化和区分Allenyne-1,6中的双键和三键,分别选择性地生成2,5-二氢呋喃和呋喃衍生物,分别制得2,5-二氢呋喃和呋喃衍生物。 -二醇。值得注意的是,仅通过将金属从金变为银就可以明显地改变化学选择性。
