The first organocatalytic approach towards synthesis of rarely explored 1,2,4-selenadiazole and thiadiazole scaffolds have been devised using corresponding carboxamides as substrates. The transformations were realized using two distinct conditions in the presence of catalytic vitamin B3 or thiourea underaerobicconditions. Developed methods overcome the associated limitations of previous reported
A convenientpreparation of 3,5-disubistituted 1,2,4-selenadiazoles was achieved by treatment of various primary selenoamides with N-bromosuccinimide.

3,5-Diaryl-1,2,4-selenadiazoles were prepared in high yields from primary selenoamides using poly[styrene(iodosodiacetate)] as oxidant. The polymer reagent could be regenerated and reused.
