Intramolecular heterocyclization with accompanying exoiminization in the reaction of ammonia with 2-chloroperfluoro-1-cyclohexene-1-thiocyanate
摘要:
the reaction of ammonia with 2-chloroperfluoro-1-cyclohexene-1-thiocyanate leads to 2-amino-7-iminoperfluoro-4,5,6-trihydrobenzo-1,3-thiazole (II) due to intramolecular heterocyclization in the Thorpe reaction with the concurrent exoiminization. Analysis of the IR spectra of (II) in CCl4 and in the solid phase indicated that molecules of (II) in the crystal form hydrogen-bonded centrosymmetric dimers (D), which are in equilibrium with free molecules of (II) in solution.

A new method has been developed for the synthesis of perfluorinated alpha,beta-unsaturated thiocyanates by the reaction of the corresponding sulfenyl chlorides with KCN in water. The thiocyanate form of perfluoro-2-methyl-2-pentene-3-thiocyanate was isomerized to the isothiocyanate form. This rearrangement is initiated by both fluoride and thiocyanate anions.
