between the propargyl triple bond and the Au(I) catalyst, in particular the character of the gold-triple bond interaction, are essential for the observed regioselectivity. Other effects, such as the presence of the solvent and the formation of a H-bond between the water molecule and the phthalimido moiety, although apparently irrelevant for the regioselectivity, have proven to be kinetically and catalytically
描述了我们对烷基和芳基取代的N-炔丙基邻苯二甲酰亚胺的 Au 催化区域选择性水合反应的研究结果,这些反应旨在选择性地形成相应的 β-邻苯二甲酰亚胺酮。实验数据,特别是观察到的区域选择性,已经在密度泛函理论 (DFT) 和分子中原子量子理论 (QTAIMS) 框架内对模型系统进行的量子化学计算定性支持。我们的研究结果表明,炔丙基三键和 Au( I) 催化剂,特别是金-三键相互作用的特征,对于观察到的区域选择性至关重要。其他影响,例如溶剂的存在以及水分子和邻苯二甲酰亚胺部分之间形成氢键,虽然显然与区域选择性无关,但已证明在动力学和催化上相当重要。
