Hydrogens located at activated positions in electrophilic arenes, e.g. ortho and para hydrogens in nitrobenzenes, can be replaced with a nucleophile moiety provided there is at least one nucleofuge X connected to the nucleophilic centre. As the group really leaving in this hydrogen substitution proc
## Abstract Azulene reacts with carbanions bearing a leaving group according to the vicarious nucleophilic substitution (VNS) scheme. Treatment of 6‐chloroazulene with such carbanions affords the VNS reaction and nucleophilic aromatic substitution (S~N~Ar) products. magnified image
