An entropy-induced selectivity switch in the gold-catalyzed hydroarylation of 2-ethynyl N-aryl indoles was discovered, and the investigation by experimental and computational mechanistic studies led to a full explanation of the observed temperature-dependent selectivity. The in this context introduced methodology allows versatile access to indolo[1,2-a]quinolines, which are highly fluorescent dyes
发现了金催化 2-乙炔基N-芳基吲哚加氢芳基化过程中熵诱导的选择性开关,并且通过实验和计算机制研究进行的研究得出了对观察到的温度依赖性选择性的完整解释。在此背景下引入的方法允许以多种方式获得吲哚并[1,2- a ]喹啉,这是一种高荧光染料,具有吸引人的光物理特性,使其成为 OLED 应用的有希望的候选者。
