of carboxylicacids using a disulfide reagent having tetrafluoropyridinyl groups is described. The light-mediated process is performed using an acridine-type photocatalyst. Primary, secondary, tertiary, and heteroatom-substituted carboxylicacids can be thiolated, and the method can be applied to the late-stage modification of a range of naturally occurring compounds and drugs. The fluorinated pyridine

A 19F NMR platform, capable of discriminating various small molecule thiols, was designed for in-cell thiol differentiation and monitoring, and further detection of the γ-GT activity, demonstrating the wide applications in thiol-related processes.

Reaction of pentafluoropyridine with nucleophilic heteroaromatics such as 4-(dimethylamino)pyridine, 4-(pyrrolidin-1-yl)pyridine, 4-(morpholin-4-yl)pyridine, 4-aminopyridine, and 3,4-diaminopyridine resulted in the formation of 4-hetarenium substituted tetrafluoropyridines. The 4-(dimethylamino)-pyridinium derivative underwent substitution reactions with isopropanolate, isopropanethiolate, and benzylthiolate
