PHOSPHORUS SULFUR AND SILICON AND THE RELATED ELEMENTS
5-Bromoacetyl-4-methyl-2-phenylthiazole reacted with dimethylsulfide, potas
sium thiocyanate, sodium benzenesulfinate and thiourea to afford products 2
-5, respectively. Hydrazonoyl bromides 7a-c obtained via reaction N-nitroso
arylacetamides with sulfonium bromide 2. Hydrazonoyl bromides were used in
synthesis of pyrrolidinopyrazolione, pyrazole, triazoline, thiadiazoline an
d 5-arylazothiazole derivatives. The structure of the newly synthesized com
pounds were confirmed on the basis of spectral, analytical analyses and alt
ernative route whenever possible.
