Reaction Intermediate of Organic Sulfur Compund Ⅱ. Nucleophilic Substitution Reaction of Disulfonyl Chloride Compounds
Dae Dong Sung*, Dae Il Jung, Kyu Chul Kim, Yang Hee Kim, Soo Dong Yoh
The nucleophilic substitution reactions of naphthalene-1,5-disulfonyl chloride and 4-fluorosulfonylbenzenesulfonyl chloride with p-substituted anilines and methyl substituted pyridines in methanol-acetonitrile mixtures and hydrolyses of those disulfonyl halides have been studied by means of conductometric and polarographic methods. A large difference in the selective parameter, ρN between mono-sulfonyl chloride and disulfonyl halide can be taken as an evidence that the second SO2Cl grolup of naphthalene-1,5-disulfonyl chloride also takes part in the reaction in contrast to sulfonyl fluoride in 4-fluorosulfonylbenzenesulfonyl chloride, which only acts as a substituent in the nucleophilic substitution reaction.
