通过Cp 2 Zr（N= CAr 2）2与PdCl（Me）（cod）（cod = 1，5-环辛烯）反应，合成了具有桥连亚烷基酰胺配体的Zr/Pd杂茂配合物Cp 2 Zr（μ-N= CAr 2）2 PdCl-（Me）（Ar = Ph，C6 H4 Me-4）. Cp 2 Zr（μ-N=CAr 2）2 PdCl（Me）配合物具有褶皱的ZrN 2 Pd环，其Zr-Pd距离分别为2.8135（5）A（Ar = Ph）和2.8416（4）A（Ar = C6 H4 Me-4）.配合物与HCl反应生成trans-PdCl（Me）（NH=CAr 2）2和Cp 2 ZrCl 2。将trans-PdCl（Me）{NH= C（C6 H4 Me-4）2 } 2的CH 2 Cl 2溶液暴露于光导致形成顺式和trans-PdCl（CHCl 2）{NH=C（C6 H4 Me-4）2 } 2的混合物。
Zr/Pd heterobimetallic complexes with bridging alkylideneamido ligands, Cp 2 Zr(μ-N=CAr 2 ) 2 PdCl-(Me) (Ar = Ph, C 6 H 4 Me-4), were prepared from the reaction of Cp 2 Zr(N=CAr 2 ) 2 with PdCl(Me)(cod) (cod = 1,5-cyclooctadiene). Cp 2 Zr(μ-N=CAr 2 ) 2 PdCl(Me) complexes have puckered ZrN 2 Pd rings with Zr-Pd distances of 2.8135(5) A (Ar = Ph) and 2.8416(4) A (Ar = C 6 H 4 Me-4), respectively. The complexes reacted with HCl to afford trans-PdCl(Me)(NH=CAr 2 ) 2 and Cp 2 ZrCl 2 . Exposure of a CH 2 Cl 2 solution of trans-PdCl(Me){NH= C(C 6 H 4 Me-4) 2 } 2 to light results in the formation of a mixture of cis- and trans-PdCl(CHCl 2 ){NH=C(C 6 H 4 Me-4) 2 } 2 .
