Polystyrene-Cross-Linking Ortho-Substituted Triphenylphosphines: Synthesis, Coordination Properties, and Application to Pd-Catalyzed Cross-Coupling of Aryl Chlorides

Polystyrene-Cross-Linking Ortho-Substituted Triphenylphosphines: Synthesis, Coordination Properties, and Application to Pd-Catalyzed Cross-Coupling of Aryl Chlorides

Polystyrene-cross-linking triphenylphosphines having methyl groups as ortho substituents were synthesized. Coordination of the polymer-bound tri(o-tolyl)phosphine-type ligand toward a Pd(II) complex was investigated by 31P CP/MAS NMR spectroscopies. Effects of the ortho-methyl-substituent were evalu...

Zusammenfassung:Polystyrene-cross-linking triphenylphosphines having methyl groups as ortho substituents were synthesized. Coordination of the polymer-bound tri(o-tolyl)phosphine-type ligand toward a Pd(II) complex was investigated by 31P CP/MAS NMR spectroscopies. Effects of the ortho-methyl-substituent were evaluated in the Pd-catalyzed cross-coupling of aryl chlorides.
