Description

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.
