Suzuki–Miyaura reaction catalyzed by a dendritic phosphine–palladium complex

Abstract

We prepared several of a new type of a dendritic ligand with a phosphine core by using tris(4-hydroxyphenyl)phosphine oxide and poly(aryl ether) dendron. In particular, when an amphiphilic dendritic phosphine–palladium complex was used as a catalyst, the aqueous media Suzuki–Miyaura reaction proceeded smoothly to provide the corresponding cross-coupling product at 50 °C. A positive dendritic effect on chemical yields was observed.
