= Ir. The neutral complexes [Py–CH2–N(R)–CH2–Pyr}MI(cod)] (M = Rh, Ir) cannot be oxidised selectively with H2O2. This is in marked contrast to the previously observed selective oxidation of the corresponding cationic complexes [Py–CH2–N(R)–CH2–Py}RhI(cod)]+. Rhodium complex 5 is an active catalyst for the stereoregular polymerisation of phenylacetylene, whereas iridium complex 6 is inactive.
[RhI(cod)]+ 和 [IrI(cod)]+ 通过新的吡啶-胺-吡咯配体 Py–CH2–N(R)–CH2–Pyr–H (HLR; R = H, Bzl, Bu ) 和相应的吡啶-胺-吡咯配体 [Py-CH2-N(R)-CH2-Pyr]- (LR-; R = H, Bzl, Bu, CH2Py) 已被研究。中性配体 HLR (R = H, Bu, Bzl) 得到 [(HLR)MI(cod)]+ (M = Rh, Ir),其中 HLR 通过吡啶氮 (NPy) 和胺氮充当双齿配体(NRamine)。[(HLH)MI(cod)]PF6 (M = Rh: [1]PF6 和 M = Ir: [2]PF6) 的晶体结构已经确定。[(HLR)MI(cod)]+ (M = Rh, Ir; R = H, Bzl, Bu) 的去质子化产生中性复合物 [(LR)MI(cod)] (M = Rh, Ir)单阴离子配体
