Synthesis and Oxydation of 1-(1,3-Thiazol-2-yl)-pyrazolidin-3-onesThe 1-(1,3-thiazol-2-yl)-pyrazolid-3-ones 4 are synthesized by reaction of 1-thiocarbamoyl-pyrazolidin-3-one 2 with α-halogenaldehydes and α-halogenketones, respectively. The structure of 4 is proved by their 1H-n.m.r. and mass spectra. Oxydative dimerisation of 4 leads to the bisazomethinimines 10. The compounds 10 represent a new type of azomethinimines with a quinoid structure.
