A novel method for the synthesis of polyhydrazide and polythiohydrazide from urea and thiourea

Abstract

A novel technique based on microwave irradiation was developed to synthesize polyhydrazide and polythiohydrazide. These polymers were readily synthesized by the reaction of aromatic and aliphatic dihydrazides with urea and thiourea. The effects of microwave irradiation time, power, solvent nature, and solid content of monomers on the inherent viscosity of the polymers were investigated. The polymers were characterized by 1 H-NMR and IR spectroscopy and elemental analysis.

A sustainable strategy for the synthesis of bis-2-iminothiazolidin-4-ones utilizing novel series of asymmetrically substituted bis-thioureas as viable precursors

“… 14 Moreover, they have been used in the manufacture of polymer 15 and as sensors for heavy metal detection. 16 In addition, the applications of thiourea derivatives have been extended to analytical chemistry; they are used for the metal ions preconcentration. 17 These fundamental characteristics of thiourea derivatives make them versatile building blocks in synthetic organic chemistry.…”
