General description
The solvolysis of 2-propanesulfonyl chloride by an addition-elimination (association-dissociation) pathway was studied.
Application
2-Propanesulfonyl chloride (isopropylsulfonyl chloride) can be used as a reactant to prepare:
- 1-Isopropylsulfonyl-2-amine benzimidazole by reacting with 2-aminobenzimidazole via N-sulfonylation reaction in the presence of a base.
- Bis(isopropylsulfonyl)disulfide, a sulfurizing agent, used to synthesize phosphorothioate oligonucleotide analogs.

Rate and product studies in the solvolyses of N,N-dimethylsulfamoyl and 2-propanesulfonyl chlorides.

Contrary to earlier suggestions of an S(N)1 pathway for solvolyses of N,N-dimethylsulfamoyl chloride (1), an extended Grunwald-Winstein equation treatment of the specific rates of solvolysis in 32 solvents shows an appreciable sensitivity towards changes in both solvent nucleophilicity and solvent
