2,4,4,6-tetrabromocyclohexa-2,5-dienone in the presence of triphenylphosphine as a regiospecific and stereoselective reagent for the nucleophilic substitution of bromine for hydroxyl

摘要

A highly reactive, regio-and stereo-specific reagent, a 2,4,4,6-tetrabromocyclohexa-2,5-dienone-triphenylphosphine complex, has been used for the first time in the nucleophilic substitution of bromine for hydroxyl in alcohols. [References: 10]
