Cyclometallated π‐allyliridium C,O‐benzoates modified with ( S )‐tol‐BINAP, which are stable to air, water, and SiO 2 , catalyze highly enantioselective N‐allylations of indoles and related azoles. This reaction complements previously reported metal‐catalyzed indole allylations in that complete levels of N versus C3 and branched versus linear regioselectivity are observed.
