= 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.

吡啶-胺-
吡咯配体 [Py- -N(R)-CH2-Pyr]- (LR-; R = H, Bzl, Bu, Py) 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
