Reaction of 5-substituted-pentamethylcyclopentadienes (C5Me5Y) with palladium chloride gave complexes of type Pd(C5Me5Y)Cl2. These complexes are probably monomeric. Consideration of the differences in the n.m.r. spectra of the complexes and free ligands leads to the conclusions that in Pd(C5Me5Y)Cl2(Y = Et, CHClMe, or CH(OR)Me) the substituent Y is exo, while in Pd(C5Me5H)Cl2 the H is endo to the metal
5-取代的五甲基环戊二烯(C 5 Me 5 Y)与氯化钯反应,得到Pd(C 5 Me 5 Y)Cl 2型配合物。这些络合物可能是单体的。考虑到络合物和游离配体的nmr光谱差异,得出的结论是,在Pd(C 5 Me 5 Y)Cl 2(Y = Et,CHClMe或CH(OR)Me)中,取代基Y为exo,而在Pd(C 5 Me 5 H)Cl 2中,H为内 与金属发生反应,并且配体在配合物形成时发生变形,可能朝向“均环丁二烯”形式。
