Sixteen 4-arylthiazol-2(3H)-ones (3) were synthesised by cyclisation of α-thiocyanatoacetophenones (1) in acid solution. They appear to prefer greatly the oxo tautomeric forms. In CCl4 solution an equilibrium between the free CO bond and a “dimeri

The reaction of 1, 3-diaryl-3-arylamino-2-thiocyanato-propanones 9 and aroylisothiocyanates was studied. 3-Aroylimino-5-arylamino-3H-1, 2, 4-dithiazoles 11 were formed in this unusual pathway by several fragmentation and rearrangement steps. The stru
