gold(I) catalysts were synthesized by immobilizing gold(I) complexes on ordered mesoporous polymer FDU-15 and characterized by XRD, N2 adsorption–desorption, FT-IR, TEM, EDS, etc. The catalytic activities of these catalysts were evaluated by the amination reactions of allylic alcohols. Among the catalysts investigated, FDU-(p-CF3Ph)2PAuCl (3d) was identified as the most efficient catalyst. Compared
将金( I )配合物固定在有序介孔聚合物FDU-15上,合成了一系列新型非均相金( I )催化剂,并通过XRD、N 2吸附-脱附、FT-IR、TEM、EDS等对其进行了表征。这些催化剂中的一部分通过烯丙醇的胺化反应进行了评估。在所研究的催化剂中,FDU-( p -CF 3 Ph) 2 PAuCl ( 3d ) 被确定为最有效的催化剂。与均相催化剂相比,非均相金的催化活性增强(I)催化剂与FDU-15的介孔结构密切相关。该催化体系适用于广泛的底物,并且可以很容易地回收和再循环至少十二次而不会显着损失催化活性。此外,进一步检查了3d的催化性能,用于分子内环化合成杂环化合物。
