Preparation and Reactivities of S,S-Diaryl-S-aminothiazynes, Ar2S(NR2)(N)

Abstract Reaction of S,S-diaryl-S-fluorothiazynes6) with cyclic secondary amines gave novel thiazynes, the corresponding S-aminothiazynes in good yields. Spectroscopic studies, measurement of pKa values, pyrolysis and alkylation reactions of the aminothiazynes were carried out.
