Furanyl-1,2,3-triazole gold(I) was designed, synthesized and characterized by X-ray crystallography, and was found to exhibit high catalytic activity for the synthesis of enones in good to high yields through a propargylic ester rearrangement and subsequent hydration. Notably, excellent E/Z selectivity was observed in these transformations. This catalyst was also effective in catalyzing the rearrangement
通过X射线晶体学设计,合成和表征了呋喃基1,2,3-三唑金(I),并发现通过炔丙基酯重排和随后的反应,该化合物对烯酮的合成具有很高的催化活性,收率高至高。保湿。值得注意的是,在这些转化中观察到优异的E / Z选择性。该催化剂在催化炔丙醇的重排和炔烃的水合作用方面也是有效的。与三唑基乙酰金(III)和其他金配合物相比,呋喃基-1,2,3-三唑金(I)能够在低温下以烯酮的E异构体为唯一产物平稳地促进这些转变。
