Back Cover: An Electrophilic Hypervalent Iodine Reagent for Trifluoromethylthiolation (Angew. Chem. Int. Ed. 12/2013)
A powerful and valuable reagent for direct trifluoromethylthiolation is reported by L. Lu, Q. Shen, and co-workers in their Communication on page 3457 ff. This new electrophilic hypervalent iodine reagent reacts with a wide range of substrates under mild conditions. The image shows the reagent and its products within the context of the ancient Chinese symbolism of the round sky and square earth.
