## Abstract Reactions of carbanions of aryl chloromethyl and dichloromethyl sulfones 3 and 4 and __tert__‐butyl chloro‐ and dichloroacetates (5 and 6) with 1‐halo‐2,4‐dinitrobenzenes 1 and 2 proceed by nucleophilic replacement of a hydrogen atom. The S~N~Ar of the halogen atom occurs to a negligibl
