合成了以甲基为邻位取代基的聚苯乙烯交联型三苯基膦。用31P CP/MAS核磁共振波谱研究了聚合物结合的三(邻甲苯基)膦配体与Pd(II)配合物的配位作用。考察了邻甲基取代基在钯催化的芳香氯交叉偶联反应中的作用。
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.
