hydrolysis of a series of platinum(IV) complexes of the general form cis, trans, cis-[PtCl 2(X) 2( (15)NH 3) 2] (X = Cl (-), O 2CCH 3 (-), OH (-)) have been followed by [ (1)H, (15)N] Heteronuclear Single Quantum Coherence NMR spectroscopy. Negligible aquation (<5%) is observed for the complexes where X = O 2CCH 3 (-) or OH (-) over 3-4 weeks. Aquation of cis-[PtCl 4( (15)NH 3) 2] ( 1) is observed, and
一系列一般形式为顺,反,顺-[PtCl 2(X)2((15)NH 3)2](X = Cl(-),O 2CCH 3的铂(IV)配合物的水合和水解(-),OH(-))之后是[(1)H,(15)N]异核单量子相干NMR光谱。在3-4周内,对于X = O 2CCH 3(-)或OH(-)的配合物,可忽略不计的水合(<5%)。观察到顺式-[PtCl 4((15)NH 3)2](1)的水合,水合速率随pH值的增加和添加0.01摩尔当量的铂(II)配合物顺式-[PtCl 2((15)NH 3)2](顺铂)。由顺式[[PtCl 4(NH 3)2]形成的第一水族物质具有一个轴向氯基团(相对于赤道NH 3配体),被一个水/羟基配体取代。观察到的第二个替换发生在赤道位置。
