An unprecedented nucleophilic displacement by bicarbonate anion, and its implications in the oxidation of alkyl toluene-p-sulphonates with dimethyl sulphoxide-sodium bicarbonate
Abstract
Bicarbonate anion is shown to be a more effective nucleophile than Me2SO when treated with the toluene-p-sulphonate (I); the elements of carbon dioxide are retained in the product as the cyclic carbonate (II).
