The reaction of malonothioamides with benzene-sulfonyl azide and 2-azido-3-ethylbenzthiazolium tatrafluoroborate gave amides of 2-diazothiomalonic acid, which underwent cyclization to a mixture of 5-N-R-amino-1,2,3-thiadiazole-4-carbothioamides and 5-amin

The reaction of 5-mercapto-1,2,3-triazole-4-carboxamide with P4S10 was studied; the mechanism of this reaction is discussed. The effect of the donor-acceptor properties of the substituents on the direction of cyclization of the intermediate malonic acid α-diazodithioamide was investigated. A new rearrangement in the 5-mercapto-1,2,3-triazole series was observed.
HETEROCYCLIZATION OF COMPOUNDS CONTAINING DIAZO AND CYANO GROUPS. 4. REACTIONS OF 2-DIAZO-2-CYANOACETIC ACID AMIDES WITH P4S10 AND THE LAWESSON REAGENT. SYNTHESIS AND RECYCLIZATION OF 5-AMINO-1,2,3-THIADIAZOLE-4-CARBOTHIOAMIDES
