Influence of conjugation on orientation in substituted nitropyridines: Vicarious Nucleophilic Substitution of Hydrogen with chloromethyl phenyl sulfone
2-Hydroxy- and 2-mercapto-5-nitropyridines as well as their O- ( and S-) substituted derivatives enter Vicarious Nucleophilic Substitution of Hydrogen (VNS) with chloromethyl phenyl sulfone. The orientation of the substitution can be controlled by varying the O- (or S-) substituent. The results of VNS in 4-methoxy-3-nitropyridine and 3-methoxy-2-nitropyridine are also reported.
