Novel reactions of perfluoroalkylphenyl sulfides with organolithium reagents

[(bpy)CuSCF3]: A Practical and Efficient Reagent for the Construction of C–SCF3 Bonds

In this account, we summarize recent work on the direct introduction of the SCF3 group by using [(bpy)CuSCF3] as trifluoromethylthiolating reagent. A number of efficient and convenient strategies have been disclosed for the synthesis of trifluoromethylthiolated compounds, including trifluoromethylthiolation of aryl, alkenyl, and alkyl halides, and arylboronic acids. These reactions afford various trifluoromethyl sulfides in good yields.

Aromatic and heterocyclic perfluoroalkyl sulfides. Methods of preparation

This review covers all of the common methods for the syntheses of aromatic and heterocyclic perfluoroalkyl sulfides, a class of compounds which is finding increasing application as starting materials for the preparation of agrochemicals, pharmaceutical products and, more generally, fine chemicals. A systematic approach is taken depending on the mode of incorporation of the SR(F) groups and also on the type of reagents used.

Highly Efficient and Functional-Group-Tolerant Catalysts for the Palladium-Catalyzed Coupling of Aryl Chlorides with Thiols

The cross-coupling reaction of aryl chlorides with aliphatic and aromatic thiols catalyzed by palladium complexes of the strongly binding bisphosphine CyPF-tBu ligand (1) is reported. Most of the reactions catalyzed by complexes of ligand 1 occur with turnover numbers that exceed those of previous catalysts by two orders of magnitude. The reactions occur with excellent yields, broad scope and high tolerance of functional groups. Coupling of aryl halides with thiols in the presence of low loadings of catalysts derived from other Josiphos type ligands, as well as ligands of other structural types, are also described.
