Abstract The synthesis of ten novel mesoionic 4??[para??substituted (H, CH3, OCH3, NO2, Cl, Br, OH, t??C4H9, C6H5, C4H9) phenyl??5??2, 4??dichlorophenyl]??1, 3??4??thiadiazolium??2?? aminides, as hydrochlorides, are described. The synthesis strategy utilized the corresponding para??substituted isothiocyanates as starting materials to obtain the thiosemicarbazides through reaction with phenylhydrazine (61–98%), which were then ...
