Metathesis of 1 with NaX (X = Br, I) gave the corresponding (methyl)bromopalladium(II) (4) and (methyl)iodopalladium(II) (5) complexes, respectively. When chloroform or chloroform/methanol solutions of 1-3 (or 5) were allowed to stand, at ambient temperatures, yellow crystalline solids were isolated in very high yields (71-88%) and were analyzed for the novel hexameric palladium(II) compounds 6-9.

一步合成三个新的P2O叔羧酸二叔膦2-(Ph2PCH2)2N} -3-(X)C6H3CO2H(X = OCH3,L1; X = OH,L2)和2-(Ph2PCH2)据报道,使用Ph 2 PCH 2 OH和适当的胺在CH 3 OH中的基于磷的曼尼希缩合反应形成的2N} -5-(OH)C 6 H 3 CO 2 H(L3)。化合物L1-L3与Pd(CH3)Cl(cod)(cod =环辛基-1,5-二烯)络合后,作为典型的kappa2-P2-配体起作用,得到中性的单核络合物Pd(CH3)Cl(L1- L3)(1-3)。1与NaX(X = Br,I)复分解分别得到相应的(甲基)溴钯(II)(4)和(甲基)碘钯(II)(5)配合物。当在室温下静置1-3(或5)的氯仿或氯仿/甲醇溶液时,分离出黄色结晶固体,收率很高(71-88%),并分析了新型六聚钯(II)化合物6-9。所报告的所有新化合物均已通过
