Evaluation of electrophilic activities of substituted nitroarenes in the VNS reaction with secondary and tertiary carbanions

Relative electrophilic activities of substituted nitroarenes in the vicarious nucleophilic substitution (VNS) reaction with carbanion of chloromethylp-chlorophenyl and bromomethyl phenyl sulfones, 1 and 2, were determined via competitive experiments. The results are in good agreement with relative activities determined earlier in the competitive experiments with carbanion of chloromethyl phenyl sulfone 3 confirming reliability of these data. On the other hand, analogous competitive experiments with tertiary carbanions of chloroform and 1-chloroethyl phenyl sulfone gave results much affected by steric effects thus the VNS reaction with these carbanions cannot be used for evaluation of electrophilic activities of nitroarenes.

Comparative Reactivity of Substituted 4-Nitrobenzylidene Dichlorides with Alkali

A comparative study of the reactions of substituted 4-nitrobenzylidene dichlorides ArCHCl2 (Ar = 3-Cl-4-NO2C6H3, 2-Cl-4-NO2C6H3, 4-NO2C6H4, 3,5-Me2-4-NO2C6H2, and 2-Me-4-NO2C6H3) with aqueous alcoholic alkali shows that chlorine substitution enhances the
