reaction must be initiated by a nucleophilic attack by the dimsylanion (CH3SOCH3) on bromine with subsequent protonation of the carbenoid intermediate. The reaction occurs rapidly (within 2 minutes) and is not inhibited by radical scavengers or in the dark. Only bromine, and not chlorine, is reduced, and the intermediate cyclopropyl anion is configurationally stable under the reaction conditions.
