手性恶唑啉基膦是铱(I)催化的亚胺不对称硅氢加成反应的有效配体,水解后以几乎定量的产率获得具有高对映选择性(高达89%ee)的相应仲胺。通过X射线分析确定了Ir(I)−恶唑啉基二茂铁基膦配合物的结构。
Chiral oxazolinylphosphines are effective ligands for the Ir(I)-catalyzed asymmetric hydrosilylation of imines to afford the corresponding sec-amines with high enantioselectivities (up to 89% ee) after hydrolysis in almost quantitative yields. The structure of an Ir(I)−oxazolinylferrocenylphosphine complex was determined by X-ray analysis.
