ABSTRACT This article describes the synthesis of a new phosphine free tetradentate Pd catalyst using dl-2,3-diaminopropionic acid. The complex was characterized by Mass, IR, and 1H NMR. The catalyst is air stable at room temperature and non-hygroscopic. Application of this new catalyst to regioselective C–H activation on 1-substituted 1,2,3-triazole and indoles with aryl iodides to get corresponding
摘要 本文描述了使用 dl-2,3-二氨基丙酸合成一种新的无膦四齿 Pd 催化剂。该配合物通过质谱、红外和 1 H NMR 表征。该催化剂在室温下对空气稳定且不吸湿。应用这种新催化剂对 1-取代的 1,2,3-三唑和吲哚与芳基碘进行区域选择性 C-H 活化,得到相应的 C-5 和 C-2 芳基化产物,收率令人满意。所有产品均通过光谱研究表征。图形概要
