Perturbation of rearrangement courses by cyclohepta-amylose
Abstract
Dibenzylmethylsulphonium fluoroborate (I), when treated with aqueous sodium hydroxide in the presence of cyclohepta-amylose, prefers the Sommelet over the Stevens rearrangement by the formation of an inclusion complex, while rate measurements reveal that cyclohepta-amylose retards slightly the rearrangement reactions.
