我们研究了由两种含炔配体衍生的一系列双核铱（II，II）和铑（II，II） 1,3 -丁二烯- 1,4 -二基配合物的反应性。新开发的配体2提供了第二代二铱配合物，对卤化物取代和乙酰基形成具有更高的反应性。由于这些配合物的1,3 -丁二烯- 1,4 -二基配体主链的影响，反应性的显著差异已经通过合成研究以及X射线晶体学和光谱分析进行了系统的研究。
We have investigated the reactivities of a series of dinuclear iridium(II,II) and rhodium(II,II) 1,3‐butadiene‐1,4‐diyl complexes derived from two types of alkyne‐containing ligands. Newly developed ligand2afforded 2nd generation diiridium complexes that have higher reactivity toward halide substitution and acetylide formation. The significant differences in reactivity, influenced by the 1,3‐butadiene‐1,4‐diyl ligand backbone of these complexes, have been systematically investigated by synthetic studies as well as X‐ray crystallographic and spectroscopic analyses.
