Distillation of a quite interesting compound, an aryl-perfluoroalkyl disulfide.
Trifluoromethyl disulfides are important as precursors of biologically active trifluoromethyl thiosulfonates and important parts of molecules being developed for modern medicinal chemistry. Good point: I recently found a cheap and well scalable method for the preparation of this functional group.
