Abstract

Liq. NH, Hz0 s, salt es described above. When 2-amino-5-mercapto-1, 3, 44hiadiazole (1) was subjected to the same reaction conditicms only two equivalents of sodium were consumed. Acidification of the salt, obtained after evaporation of the ammonia, yielded equal amounts of 2-amino-1, 3, Ir_thiadiazole(12) and starting material. Here, too, the first equivalent of sodium is used to generate the corresponding thiolate (8). The second ...
