## Abstract The effect on electrophilic activity of substituents located __para__, __ortho__, and __meta__ to the nitro group of nitrobenzenes was determined by using vicarious nucleophilic substitution of hydrogen (VNS) with the carbanion of chloromethyl phenyl sulfone (**1**) as the model process
Stereochemistry of the reactions of methyl-, ethyl-, 2propyl-, and 1 ,I -dimethylethylsulfinyl phenylmethyl carbanions with deuterium oxide and methyl iodide in tetrahydro furan have been studied. The 2-propylsulfinyl phenylmethyl carbanion exerts abnormal behavior in the sense that the alkyl substi
