Terephthalaldehyde: An Effecient Key Precursor for Novel Synthesis of Some Interesting Bis‐thiazoles and Bis‐triazolopyrimidinones

Novel bis‐thiazoles were synthesized in high and efficient yields from the reaction of thiosemicarbazones with halogenated compounds. Also, new bis‐triazolopyrimidines were prepared from the reaction of hydrazonoyl chlorides with bis‐thione derivative. All prepared compounds were fully characterized by spectral methods. The synthesized bis‐compounds will be attractive species for the medicinal researchers to investigate their biological activity.
