Homogeneous Dihydroxylation of Olefins Catalyzed by OsO₄²⁻ Immobilized on a Dendritic Backbone with a Tertiary Nitrogen at Its Core Position

Abstract

OsO₄²⁻ immobilized on a poly(benzyl ether) dendrimer 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.
