The novel dimeric iodo-iridium(III) complex, [Ir(Cp*CONMe2)I2]2, (Cp*CONMe2 = η5-N,N-2,3,4,5-hexamethylcyclopenta-2,4-diene carboxamide) bearing an amide moiety within the tetramethylcyclopentadiene ring, has been synthesised and characterised. The ligand Cp*CONMe2 is synthesised as two regioisomers, however the 2-substituted isomer exists as two distinguishable conformers due to restricted rotation
新型二聚碘铱 ( III ) 配合物 [Ir(Cp*CONMe 2 )I 2 ] 2 , (Cp*CONMe 2 = η 5 - N,N -2,3,4,5-hexamethylcyclopenta-2,4 -diene carboxamide) 在四甲基环戊二烯环内带有酰胺部分,已被合成和表征。配体 Cp*CONMe 2被合成为两个区域异构体,但是由于围绕酰胺羰基碳和环碳的旋转受限,2-取代异构体作为两个可区分的构象异构体存在。Cp*CONMe 2和 Cp*的相对酸度通过它们的相对 H/D 交换率进行比较。N,N的铱络合物-2,3,4,5-hexamethylcyclopenta-2-4-diene carboxamide [IrCp*CONMe 2 ] 和 ( R,R )-1,2-diphenyl- N '-tosylethane-1,2-diamine (( R , R )-TsDPEN)
