Nitroaromatics substituted with electron-acceptor or electron-donor groups undergo vicarious nucleophilic substitution with the lithium salt of dichloromethane to provide chloromethyl-substituted nitroaromatics in good to high yields. The methodology represents a new strategy for the synthesis of benzyl chlorides.
