Abstract
5-Bromoacetyl-4-methyl-2-phenylthiazole reacted with dimethylsulfide, potassium thiocyanate, sodium benzenesulfinate and thiourea to afford products 2–5, respectively. Hydrazonoyl bromides 7a-c obtained via reaction N-nitrosoarylacetamides with sulfonium bromide 2. Hydrazonoyl bromides were used in synthesis of pyrrolidinopyrazolione, pyrazole, triazoline, thiadiazoline and 5-arylazothiazole derivatives. The structure of the newly synthesized compounds were confirmed on the basis of spectral, analytical analyses and alternative route whenever possible.
