We report a general and rapid chemoselective Kumada–Tamao–Corriu (KTC) cross‐coupling of aryl bromides in the presence of chlorides or triflates with functionalized Grignardreagents at 0 °C in 15 min by using Pd‐PEPPSI‐IPentCl (C4). Nucleophiles and electrophiles (or both) can contain Grignard‐sensitive functional groups (‐CN, ‐COOR, etc.). Control experiments together with DFT calculations suggest
