Basic catalysis in the trapping of sulphenes
Abstract
The trapping of phenylsulphene with alcohols or aromatic amines is catalysed by amines; in the reaction of phenylsulphene with a mixture of propan-2-oland p-toluidine, changing the catalyst from a strong to a weak tertiary amine changes the chief component of the product from the sulphonamide to the ester.
