Abstract
The 3-amino- and 3-hydroxythioacrylamides were
obtained by deprotonation and hydrolysis of l-mercaptotrimethinium
perchlorates respectively. In this researeh,
both the thioacrylamides and the mercapto salts were used +;
as starting materials to implement the synthesis of
2-amino~5-nitrothiophenes, 5-aminopysazoles, aminothiopyrylium
salts and 5-aminoiso::.:azoles • For the amino. itrothiophenes and aminopyrazoles 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.
