Vicarious Nucleophilic Substitution of Hydrogen in Nitropyridines by α-Chloroalkyl Phenyl Sulfone Carbanions
Nitropyridines and chloronitropyridines react with carbanions of α-chloroalkyl phenyl sulfones yielding products of the vicarious nucleophilic substitution of hydrogen at positions ortho and para to the nitro group.A general rule that the vicarious substi
