Synthesis and liquid crystalline studies of some heterocyclic compounds with lateral long chain substituents
The condensation of dithio-oxamide with aromatic aldehyde was first described by Ephraimtli. However, the product was not correctly identified until 1960, when Johnson and Ketcham121 reported the actual chemical structural of this condensation based on spectral data. The thiazolo[5,4-d] thiazole is a fused ring system, which is stable and resistant to the chemical attack.
