5-Amino-1,2,3,4-thiatriazole: Its Acylation with Chloroformates and Chlorothioformates as a Route to 1,2,4-Thiadiazoles and 1,6,6a,Δ4-Trithia-3,4-diazapentalenes

Pyridine catalyzed acylation of 5-amino-1,2,3,4-thiatriazole with chloroformates and chlorothioformates afforded 3,5-bis(ethoxycarbonylamino)-1,2,4-thiadiazoles in the former and 2,5-bis(phenoxy)-1,6,6a,Δ⁴-trithia-3,4-diazapentalenes in the lat
