whereas direct substitution gives high yield. [RaaiR/ = p-R-C6H4-N=N-C3H2-NN-1-R/, (1-3), abbreviated as N,N/-chelator, where N(imidazole) and N(azo) represent N and N/, respectively; R = H (a), Me (b), Cl (c) and R/ = Me (1), CH2CH3 (2), CH2Ph (3), OSO2CF3 is the triflate anion, bpy is 2,2´-bipyridine]. The 1H NMR spectral measurements suggest methylene, –CH2–, in RaaiEt gives a complex AB type multiplet
[Au(bpy)Cl 2 ]PF 6与AgOTf反应,然后添加配体,导致[Au(bpy)(RaaiR / )] 产率低,而直接取代则产率高。[RaaiR / = p -RC 6 H 4 -N=NC 3 H 2 -NN-1-R / , ( 1-3 ),缩写为N,N / -螯合剂,其中N(咪唑)和N(偶氮)分别代表 N 和 N /;R = H ( a )、Me ( b )、Cl ( c ) 且 R / = Me ( 1 )、CH 2 CH 3( 2 ),CH 2 Ph ( 3 ),OSO 2 CF 3是三氟甲磺酸根阴离子,bpy 是2,2´-联吡啶]。1 H NMR 光谱测量表明,RaaiEt 中的亚甲基-CH 2 - 给出了复杂的AB 型多重峰,而RaaiCH 2 Ph 中则显示了AB 型四重峰。13 C NMR谱反映了分子骨架。在本配合物的1 H- 1 H COSY 谱和本配合物的1
