the generality of gold versus silver catalyzed intramolecular hydroarylation reactions of 3-[(3-arylprop-2-ynyl)oxy]benzene derivatives in terms of rings substitution were investigated. Only products deriving from 6-endo cyclization were exclusively formed. The features of substituents had a considerable effect on the reaction outcome in the presence of silver catalysis, whereas gold catalysis revealed
研究了金与银催化的3-[((3-芳基丙-2-炔基)氧基]苯衍生物在环取代方面的分子内氢芳基化反应的范围和一般性。仅形成了6-内环化衍生的产品。取代基的特征在存在银催化的情况下对反应结果有相当大的影响,而金催化显示出反应性和选择性的独特混合物,并且是带有电子缺陷的芳烃的起始底物的分子内氢化反应的唯一选择。
