Cobalt‐catalyzed CH arylations enabled the synthesis of biaryl tetrazoles, which are key structural motifs in antihypertensive angiotensin‐II‐receptor blockers. Thus, weakly‐coordinating benzamides were employed for step‐economical CH arylations with ample scope. Further, a low‐valent NHC complex enabled first cobalt‐catalyzed CH functionalization by tetrazole assistance.
