Metal ion electrophilic catalysis (Li+ > Na+ ? K+) has been found in ring-opening reactions of 1,2-epoxides 1-5 by metal halides MHa1 in ionic liquids. The results have been rationalized on the basis of a transition state where the cation M+ stabilizes the negative charge developing on the oxygen atom of the oxirane ring while favoring the nucleophilic attack at the adjacent carbon by the ion-paired anion Hal -.
