Antimony Trichloride Catalysed Reactions on Terpenoids

Unlike homoallylic alcohols which undergo addition to the olefin, allylic alcohols undergo substitution reaction in antimony trichloride catalysed reaction.This reaction involves a carbonium ion mechanism.However, there is a high degree of selectivity in the formation of the reaction products which have some differences in their stabilities.In case of lactones, products arising from alkyl oxygen and acyl oxygen cleavages are formed depending on the stability of the ions obtained by these cleavages.
