Third times a charm: A new Pd–NHC catalyst, Pd‐PEPPSI‐IPentCl, has been developed for applications in amination reactions for the preparation of triarylamines. The catalyst can be used under mild conditions (carbonate base/dioxane, 80 °C) to perform multiple aminations in sequence from simple aniline derivatives that contain highly base‐sensitive functional groups.
第三次魅力:开发了一种新的Pd-NHC催化剂Pd-PEPPSI-IPent Cl,用于制备三芳基胺的胺化反应中。该催化剂可在温和条件下(碳酸盐碱/二恶烷,80°C)使用,以从含有高度碱敏感官能团的简单苯胺衍生物开始依次进行多种胺化反应。
