The reactions of an S-bridged trinuclear palladium(II) complex, [Pd(3)(D-pen-N,O,S)(3)] (D-H(2)pen = D-penicillamine), with ethylenediamine (en) and racemic (R,R/S,S) 1,2-cyclohexanediamine (chxn) in water gave mononuclear palladium(II) complexes, [Pd(D-pen-N,S)(en)] (1) and [Pd(D-pen-N,S)(chxn)] (2), respectively. Of two diastereomers, [Pd(D-pen-N,S)(R,R-chxn)] (2(R)) and [Pd(D-pen-N,S)(S,S-chxn)] (2(S)), possible for 2, 2(S) was exclusively isolated in a high yield.
S-桥联三核钯(II)配合物[Pd(3)(D-pen-N,O,S)(3)](D-H(2)pen=D-青霉胺)与乙二胺(en)和外消旋(R,R/S,S)1,2-环己二胺(chxn)在水中反应,分别得到单核钯(II)配合物[Pd(D-pen-N,S)(en)](1)和[Pd(D-pen-N,S)(chxn)](2)。在两种非对映异构体[Pd(D-pen-N,S)(R,R-chxn)](2(R))和[Pd(D-pen-N,S)(S,S-chxn)](2(S))中,可能的 2,2(S)以高产率被选择性地分离出来。
