Chlorosulfonyl isocyanate Chemical Properties,Uses,Production
Chemical Properties
Clear liquid, colourless
Uses
Chlorosulfonyl isocyanate, a highly reactive chemical for chemical synthesis, is used as an intermediate used for production of antibiotics (Cefuroxime, penems), polymers as well as agrochemicals. Product Data Sheet
Uses
Employed in a regio- and diastereoselective introduction of a protected amino group in a synthesis of chiral, polyhydroxylated piperidines. Generation of ureas from amino groups in a synthesis of benzimidazolones.
General Description
Chlorosulfonyl isocyanate reacts with hydrocarbon alkenes via stepwise dipolar pathway to give N-chlorosulfonyl-β-lactams.
