Notes:
Proton and 13C NMR chemical shifts and coupling constants of 2-aminothiazoles and 2-iminothiazolines are reported. The one-bond C—H, vicinal H-H, geminal C—H and vicinal C—H coupling constants of 2-aminothiazoles and 2-iminothiazolines are discussed in terms of tautomerism between amino forms and imino forms. The site of charge centered either on the ring nitrogen or the exocyclic nitrogen atom in the protonated 2-aminothiazole is also discussed.
