air‐stable Pd trimer and presents unambiguous reactivity data of its privileged capability to differentiate C−I over C−Br bonds in C−C bond formations (arylation and alkylation) of polyhalogenated arenes, which typical Pd0 and PdI‐PdI catalysts fail to deliver. Experimental and computational reactivity data, including the first location of a transition state for bond activation by the trimer, are presented
尽管人们越来越关注在催化中利用一种以上金属的协同效应,但除双金属体系外,人们所知甚少。该报告描述了直接进入空气稳定的Pd三聚体的方法,并提供了明确的反应性数据,该数据具有在多卤代芳烃的C-C键形成(芳构化和烷基化)中区分C-1与C-Br键的特权。0和Pd I -Pd I催化剂无法输送。给出了实验和计算反应性数据,包括三聚体激活键的过渡态的第一个位置,支持直接的三聚体反应性是可行的。
