A new shelf-stable and easily scalable difluoromethylthiolating reagent S-(difluoromethyl) benzenesulfonothioate (PhSO2SCF2H) was developed. PhSO2SCF2H is a powerful reagent for radical difluoromethylthiolation of aryl and alkyl boronic acids, decarboxylative difluoromethylthiolation of aliphatic acids, and a phenylsulfonyl-difluoromethylthio difunctionalization of alkenes under mild reaction conditions.

A BrØsted acid-catalyzed electrophilic trifluoromethylthiolation of indoles under mild conditions is described. The reaction was insensitive to moisture and oxygen, that should allow for easy handling. In addition, the reaction is compatible with a variety of functional groups. [ABSTRACT FROM AUTHOR]

A silver-catalyzed decarboxylative trifluoromethylthiolation of secondary and tertiary carboxylic acids under mild conditions tolerates a wide range of functional groups. The reaction was dramatically accelerated by its performance in an aqueous emulsion, which was formed by the addition of sodium dodecyl sulfate to water. It was proposed that the radical, which was generated from the silver-catalyzed decarboxylation in the 'oil-in-water' droplets, could easily react with the trifluoromethylthiolating reagent to form the product.

Sulfur and friends: A new electrophilic hypervalent iodine reagent 1 has been developed for direct trifluoromethylthiolation. A variety of nucleophiles, including β‐ketoesters, aldehydes, amides, aryl or vinyl boronic acids, and alkynes, reacted with 1 under mild conditions to give the corresponding trifluoromethylthiolated compounds in good to excellent yields.

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. [ABSTRACT FROM AUTHOR]
