Abstract: The 3-amino- and 3-hydroxythioacrylamides were obtained by deprotonation and hydrolysis of 1-mercapto-trimethinium perchlorates respectively. In this research both the thioacrylamides and the mercapto salts were used as starting materials to implement the synthesis of 2-amino-5-nitrothiophenes, 5-aminopysazoles, amino-thiopyrylium salts and 5-aminoisouazoles. Eor the amino.itrothiophenes and aminopyrazolee attempts made to solate reaction intermediates were successful and acceptable mechanisms have been suggested. In almost all cases reactions were rapid and yields were high.
