The synthesis of SCF3 as well as SeCF3 isosteres of two OCF3-containing drugs was achieved through visible light and copper-catalyzed processes. Herein, we show that chalcogen replacement modulates physicochemical and ADME properties without introducing intrinsic liabilities. The SCF3 and SeCF3 groups are more lipophilic than their oxygen counterpart; however, microsomal stability is unchanged, indicating that these molecular changes may be beneficial for in vivo half-life. Enabled by modern synthetic methods, we present the chalcogen-CF3 groups as potential key players for future fluorinated pharmaceuticals.

A convenient and efficient method for the construction of aryl trifluoromethyl selenoethers from the corresponding aryl halides in the presence of Ni(COD)2 and an appropriate ligand is reported. Various aryl iodides, bromides, and chlorides were smoothly converted in this reaction by simply varying the ligand, which afforded aryl and heteroaryl trifluoromethyl selenoethers in good to almost quantitative yields. The reaction was also applicable to the synthesis of druglike molecules. This work is the first report for trifluoromethylselenolation of aryl chlorides. Advantages of the present Ni-catalyzed approach include mild reaction conditions, good functional group tolerance, inexpensive reagents, easy operation, and no use of additional additives. This protocol allows for a straightforward and reliable access to trifluoromethyl selenides that are latent screening candidates for new pharmaceuticals and agrochemicals.

Building on our recent disclosure of catalysis at dinuclear PdI sites, we herein report the application of this concept to the realization of the first catalytic method to convert aryl iodides into the corresponding ArSeCF3 compounds. Highly efficient C-SeCF3 coupling of a range of aryl iodides was achieved, enabled by an air-, moisture-, and thermally stable dinuclear PdI catalyst. The novel SeCF3-bridged dinuclear PdI complex 3 was isolated, studied for its catalytic competence and shown to be recoverable. Experimental and computational data are presented in support of dinuclear PdI catalysis.
