Synthesis of Dendrimers with a Bidentate Phosphine Core Ligand Having Carboxy Groups at the Peripheral Layer and Their Application to Aqueous Media Cross-Coupling Reactions

Abstract

We prepared a series of dendrimers with a bidentate phosphine core ligand having carboxy groups at the peripheral layer. By employing the corresponding water-soluble dendritic phosphine–palladium complex as a catalyst, the aqueous media Suzuki–Miyaura reaction and Tsuji–Trost reaction proceeded to provide the corresponding cross-coupling product.
