Nucleophilic substitution at sulphur with retention of configuration
Abstract
Optically active methyl p-tolyl sulphoxide and methyl butyl sulphoxide are shown to react with NN′-bis-(toluene-p-sulphonyl) sulphur di-imide in benzene solution to the corresponding N-(toluene-p-sulphonyl)-sulphimides with retention of configuration at sulphur.
