The dirhodium(II) carboxylate complex Rh2(esp)2 catalyzes the sulfoxidation of organic sulfides in the presence of tert-butyl hydroperoxide as the oxidant. As the rhodium catalyst is able to precipitate as a Rh2(esp)2-sulfoxide complex following the reaction, its separation and reuse is very convenient without considerable loss of activity.
