size of the ligand and the substituents of the palladacycle. Diffusion-ordered nuclear magnetic resonance spectroscopy experiments are used to measure the diffusion coefficients and propose the nuclearity of these complexes in solution. Density functional theory calculations show that steric and electronic (transphobia) effects are responsible for the unprecedented observed reactivity differences. A mechanism
将一分子炔插入由
高藜芦胺和芬特明衍生的保拉达环的Pd-C键中而产生的八元保拉达环与中性N-和P-供体
配体反应,生成单核或不寻常的双核配合物,其中含有
乙烯基芳基乙基
氨基桥,取决于palladacycle的
配体和取代基的大小。扩散有序核磁共振光谱实验用于测量扩散系数,并提出溶液中这些配合物的核化性质。密度泛函理论计算表明,空间效应和电子效应(恐惧症)是造成前所未有的观察到的反应性差异的原因。提出了形成异常双核配合物的机制。
