Abstract

Summary The Jacobsen reaction on the bromotetrarnethylbenzenes consists in the migration of a bromine atom to give the corresponding dibromo compound and prehnitene sulfonic acid. The usual by-products of sulfur dioxide and a brown amorphous material are obtained. The first step in the reaction is sulfonation, and the sulfonic acid is the rearranging molecule.
