This is the first report on the PEG-300-mediated one-pot synthesis of 2-(2-hydrazinyl) thiazole derivatives from ketones, thiosemicarbazide, and α-halo ketones. Here PEG-300 acts as a solvent as well as supporting catalyst. Formation of compounds was confirmed by IR, 1H NMR, 13C NMR, and mass spectroscopic studies. A series of 2-(2-hydrazinyl) Thiazole derivatives have been synthesized from substituted
