well as propargyl ethers with differently substituted phenols under ambient atmosphere in aqueous medium has been developed using β‐cyclodextrin hydrate as an efficient, recyclable and stable catalyst. This is the first report where β‐cyclodextrin hydrate acted as a catalyst for an organic transformation but β‐cyclodextrin alone failed.
β-环糊精水合物已开发出一种经济高效,操作简单且生态兼容的方案,用于在环境介质中于环境气氛下通过炔丙醇以及炔丙基醚与不同取代的苯酚的反应一锅合成光致变色的吡喃作为一种高效,可回收和稳定的催化剂。这是第一个报道,其中β-环糊精水合物充当有机转化的催化剂,但仅β-环糊精就失败了。
