Chlorosulfonyl isocyanate (CSI) is a sluggish electrophile in reactions with electron-deficient alkenes or with many monofluoroalkenes. The efficiency of these reactions is improved at temperatures between –15 and 25 °C because, at these temperatu

Chlorosulfonyl isocyanate (CSI) is reported to react with hydrocarbon alkenes by a stepwise dipolar pathway to give N-chlorosulfonyl-β-lactams that are readily reduced to β-lactams. Substitution of a vinyl hydrogen for a vinyl fluorine changes the

The equilibrium between two separate reactants and a complex or SET intermediate formed by them shifts towards the unimolecular intermediate between -15 and 25°, therefore, the efficiency of the electrophile (II) is improved under the reaction condi
