An unsymmetrical 2-(diphenylphosphino) aminobenzothiazole (DPA) was used to synthesize a heterogeneous and recyclable palladium composite through co-doping C3N4. The resulting palladium composite (DPA-Pd@g-C3N4) was carefully characterized by scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy, X-ray diffraction, N2 sorption isotherms, thermogravimetricanalysis
使用不对称的2-(二苯基膦基)氨基苯并噻唑(DPA)通过共掺杂C 3 N 4合成非均相且可回收的钯复合材料。通过扫描电子显微镜、透射电子显微镜、X 射线光电子能谱、X 射线衍射、N 2吸附等温线、热重分析和能量色散 X 射线光谱对所得钯复合材料 (DPA-Pd@gC 3 N 4 ) 进行了仔细表征. 此外,复合 DPA-Pd@gC 3 N 4通过借氢策略成功应用于2-氨基吡啶与苯甲醇反应合成N-取代氨基吡啶衍生物。 图形概要 通过C 3 N 4掺杂Pd合成了相应的钯非均相催化剂,对合成N-取代氨基吡啶具有较高的催化活性和良好的回收性能。
