## Abstract Reaction of isoselenocyanates with hydrazine or aryl hydrazines generates the corresponding selenosemicarbazides which are coupled with ethyl chloroacetate to yield 1,3โselenazolidinโ4โones (III) and (VI).

โฆ Synopsis
An efficient and regioselective synthesis of 2-imino-1,3-selenazolidin-4-ones and 2-amino-1,3,4-selenadiazin-5-ones was achieved via one-pot reaction of isoselenocyanates, hydrazines, and ethyl chloroacetate or chloroacetyl chloride, respectively. Plausible mechanisms for these transformations were given.
