Rhodium(I) and iridium(I) imidazo[1,5-a]pyridine-1-ylalkylalkoxy complexes: Synthesis, characterization and application as catalysts for hydrosilylation of alkynes
Rh(I) and Ir(I) complexes bearing imidazo[1,5-a]pyridine-1-ylalkyl alcohol as chelating NˆO-monoanionic ligands were prepared as thermally stable compounds. Their spectroscopic properties and structures were determined based on IR and NMR spectra and X-ray analyses. The Rh(I) complexes were used as catalysts for the hydrosilylation of alkynes. The catalytic activities of the complexes were highly influenced
制备具有咪唑并[1,5 - a ]吡啶-1-基烷基醇作为螯合N = O-单阴离子配体的Rh(I)和Ir(I)配合物,作为热稳定化合物。基于IR和NMR光谱以及X射线分析确定它们的光谱性质和结构。Rh(I)配合物用作炔烃氢化硅烷化的催化剂。配合物的催化活性受到其芳环上取代基的高度影响。在更长的反应时间下,在较高的温度下可以实现乙烯基硅烷的高度E选择性形成。
