A protocol for the gram-scale synthesis of polyfluoroaryl sulfides via an S(N)Ar step

Polyfluoroaryl sulfide is one of the prevalent motifs ubiquitous in materials and pharmaceutical chemistry. We herein describe a simple yet efficient procedure for their synthesis from readily available thiols and polyfluoroarenes via an S(N)Ar step. We detail specific steps for a gram-scale preparation of 2-((perfluoropyridin-4-yl)thio)benzo[d]thiazole 3 from mercaptobenzothiazole 1 and pentafluoropyridine 2. For complete details on the use and execution of this protocol, please refer to Liao et al. (2022).(1)
