反式-[Pd(CH 2 C 6 H 4 Y)(X)(PR 3)2 ](2)型苄基钯配合物与异氰酸酯的反应产生亚氨基配合物,其以相应亚胺的平衡混合物形式存在于溶液中[[ Pd(C(NR')CH 2 C 6 H 4 Y)(X)(PR 3)2 ],3-im)和烯胺([Pd(C(NHR'CHC 6 H 4 Y)(X)(PR 3)2,3烯)互变异构体。尽管平衡常数受苯环(Y)上的取代基所施加的电子效应的显着影响,但金属片段的作用较不明显,且受空间因素支配。这两种互变异构形式也可在固态中发现,和类型的复合物的X射线结构2,3-IM,和-3-烯已被确定。
mono(phosphorus ligand)palladium(0) complexes catalyzed alkene insertions into hydrogen–tungsten bonds. These insertions using WHCp(CO)3 with ethyl acrylate and dimethyl fumarate smoothly gave the corresponding alkyltungsten complexes. Kinetic studies involving the stoichiometric reactions and DFT calculations suggest the following steps: (i) formation of a mono(phosphorus ligand)mono(alkene)palladium(0) species
