bromides and chlorides has been achieved under the most mild temperatures yet reported (i.e., room temperature to 40 °C). The bulk afforded by the di‐2,6‐(3‐propylphenyl)imidazolium‐derived Pd‐PEPPSI‐IPent catalyst is believed to actively promote the critical reductive elimination step of the catalytic cycle, thereby eliminating the formation of poisonous off‐cycle dimeric resting states that have plagued
