with a tertiary nitrogen at its core position efficiently catalyzed the homogeneous dihydroxylation of olefins with a low level of osmium leaching. The dendritic osmium catalyst could be applied to the wide range of olefins. Furthermore, the dendritic osmium catalyst was recovered by reprecipitation and then reused up to five times.
OsO(4)(2-)固定在聚(
苄醚)树枝状聚合物上,在其核心位置带有叔氮,可有效催化烯烃的均相二羟基化,并具有低
水平的low浸出。树枝状catalyst催化剂可应用于各种烯烃。此外,通过再沉淀回收树枝状催化剂,然后重复使用多达五次。
