trifluoromethylthiolating reagent. This procedure provides a straightforward synthetic method for heteroaryl trifluoromethyl sulfides from readily available, simple starting materials. The reaction demonstrates a broad substrate scope and tolerates a wide array of functional groups, including nitrile, ester, chloro, nitro, or methoxy substituents.

the development of a mild and fast photocatalytic trifluoromethylation of thiols. The combination of commercially available Ru(bpy)3Cl2, visible light and inexpensive CF3I gas proved to be an efficient method for the direct trifluoromethylation of thiols. The protocol is demonstrated on a wide range of aromatic, hetero-aromatic and aliphatic substrates in both batch and continuous microflow (32 examples

Trifluoromethyl phenyl sulfone is traditionally a nucleophilic trifluoromethylating agent. Herein, we report the first example of the use of trifluoromethyl phenyl sulfone as a trifluoromethylradical precursor. Arylthiolate anions can form electron donor–acceptor (EDA) complexes with trifluoromethyl phenyl sulfone, which can undergo an intramolecular single electron transfer (SET) reaction under visible

A practical sliver-catalyzed fluoroalkylation of aryl-, heteroaryl- and allcylthiols has been developed. The reaction has a good functional-group tolerance and excellent selectivity. A variety of stable and solid fluoroalkanesulfinates including di- and perfluoroalkanesulfinates can be employed. This methodology provides a straightforward and streamlined access to perfluoroallcylthiolated organic molecules.[GRAPHICS](C) 2016 Elsevier B.V. All rights reserved.
