Studies on gold(III) coordination of a series of new chiral polydentate (X,)N,O‐pyridine based ligands are reported. Successful coordination afforded novel chiral N,N,O‐tridentate Au(III) complexes with the 2‐pyridyl‐6‐[(1S,2S,5R)‐neomenthol‐1‐yl]pyridine ligand (1H, 13C, 15N NMR, HRMS, IR, XRD). The chiral 2‐aryl‐6‐alkylpyridine alcohol ligands were prepared from 2,6‐dibromopyridine, (–)‐menthone
报道了一系列新型手性多齿(X,)N,O-吡啶基配体的金(III)配位研究。成功的配位提供了新型手性N,N,O-三齿Au(III)配合物与2-吡啶基-6-[(1 S,2 S,5 R)-新薄荷醇-1-基]吡啶配体(1 H,13 C,15 N NMR,HRMS,IR,XRD)。手性2-芳基-6-烷基吡啶醇配体是由2,6-二溴吡啶,(-)薄荷酮或(+)樟脑和芳基硼酸制备的。新的N,N,O连接的金(III)络合物具有高催化活性,在环丙烷化测试反应中的性能优于AuCl 3。
