Selective functionalization of alkenes via acetoxylation is an important organic transformation, since esters formed in the reaction provide a variety of organic derivatives by simple nucleophilic exchange. 1 Earlier attempts of acetoxylation of higher alkenes by Lewis acids proceeded with concomitant isomerization to afford an isomeric mixture of acetoxylated derivatives2-4. Montmorillonite, an acid smectite clay de- signed to obtain higher ...
