Abstract
The reactions of 5-substituted dibenzothiophenium salts with aryllithiums have been found to yield ring-opening products (I), ligand-exchange ring-opening products (II) and other products, as shown in Table I. The formation of these compounds supports the assumption of the pseudorotation of pentacoordinated sulfur intermediates in these reactions.Keywords
