The simple inorganic rhodium salt RhCl3·3H2O was used as a catalyst to achieve the thiolation of acrylic acids, with a series of (Z)-alkenyl sulfides being obtained exclusively. It is noteworthy that [Cp*RhCl2]2 was not as efficient as RhCl3·3H2O in this strategy. Furthermore, the products could be transformed conveniently into biologically and pharmacologically useful thioflavones.
Carbonylative Synthesis of 3-Substituted Thiochromenones via Rhodium-Catalyzed [3 + 2 + 1] Cyclization of Different Aromatic Sulfides, Alkynes, and Carbon Monoxide

We have developed a rhodium-catalyzed carbonylative annulation methodology for the direct preparation of thiochromenones. With nonactivated aromatic sulfides and terminal alkynes as the substrates, the desired sulfur-containing six-membered heterocycles were prepared effectively via [3 + 2+1]-type annulation.
