| Abstract: | It presented the synthesis of 2-aroylamino-5-(a-naphthalenemthyl)-l, 3, 4-thiadiazoles (3a-31) by the acid catalytic cyclization of l-(a-naphthaleneacetyl)-4-aroylthiosemicarbazides (2a-21) which were prepared by the nucleophilic addition reaction of a-naphthaleneacetyl hydrazide and aroyl-isothiocyanide. Twelve new compounds were prepared and their strutures were characterized by means of elemental analysis, 'H-NMR, IR and MS. |
