A supramolecular flask device with inwardly oriented Au^I and P=O is described, including a description of its catalytic proclivity in the regioselective hydration of specific alkynes. The bifunctional cavity favors selective folding of a single side chain of unsymmetrical alkynes through host–guest interactions, which skillfully directs the water molecule to one carbon atom of the triple bond.

用于特定炔烃区域选择性水合的金属催化空泡的合理设计

描述了具有向内取向的Au ^I和P = O的超分子烧瓶装置，包括其在特定炔烃的区域选择性水合中的催化倾向性的描述。双功能腔体有利于通过主体与客体之间的相互作用选择性地折叠不对称炔烃的单侧链，从而巧妙地将水分子引导至三键的一个碳原子上。
