Copper-Mediated Trifluoromethylthiolation of Heteroaryl Bromides

An efficient protocol for the copper-mediated trifluoromethylthiolation of heteroaryl bromides has been achieved using the copper complex (bpy)Cu(SCF3) as 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.

Trifluoromethylation of thiophenols and thiols with sodium trifluoromethanesulfinate and iodine pentoxide

A selective and facile trifluoromethylation process for a wide range of thiophenols and thiols under metal free conditions has been developed using two simple and safe solids, sodium trifluoro-methanesulfinate and iodine pentoxide, via the radical process.

A mild and fast photocatalytic trifluoromethylation of thiols in batch and continuous-flow

S-CF3 bonds are important structural motifs in various pharmaceutical and agrochemical compounds. However, their preparation remains a major challenge in synthetic organic chemistry. Here, we report 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, 52-98% yield). Process intensification through continuous microflow application resulted in a 15-fold increase in production rate (0.25 mmol min-1) due to improved gas-liquid mass transfer, enhanced irradiation as well as convenient handling of the gaseous CF3 source. Furthermore, the efficiency of the flow process allowed to reduce the amount of CF3I (1.1 equivalent) to reach full conversion. This journal is
