Hydroxyapatite Supported Palladium Catalysts for Suzuki-Miyaura Cross-Coupling Reaction in Aqueous Medium

Catalyst 1 was prepared by the immobilisation of [Pd(COD)Cl sub(2)] on hydroxyapatite. Catalyst 2 was prepared by reduction of 1 with sodium borohydride in ethanol. With 1 electronically neutral, electron rich, electron poor or sterically hindered aryl boronic acids and aryl halides underwent Suzuki...

Zusammenfassung:Catalyst 1 was prepared by the immobilisation of [Pd(COD)Cl sub(2)] on hydroxyapatite. Catalyst 2 was prepared by reduction of 1 with sodium borohydride in ethanol. With 1 electronically neutral, electron rich, electron poor or sterically hindered aryl boronic acids and aryl halides underwent Suzuki-Miyaura crosscoupling in water as the solvent. Catalyst 1 with Pd super(2+) exhibited much better catalytic activities than 2.
