An efficient one-pot synthesis of 2-amino-1,3,4-selenadiazoles.

An efficient one-pot synthesis of 2-amino-1,3,4-selenadiazoles from isoselenocyanates, hydrazine hydrate and aromatic aldehydes has been developed. This approach provides a simple, mild and facile way to construct various derivatives in moderate to good yields (57- 82%). A plausible mechanism is proposed for the formation of the target products.
