Abstract
1,3-Selenazoles were Synthesized from 3-bromo acetyl coumarin and selenourea in the presence of CuPy2Cl2 under solvent-free conditions at ambient temperature. The pure products were identified by spectral data.

Notes
Note. Reaction conditions: 3-bromo acetyl coumarin (1 mmol), selenourea (1.2 mmol), and CuPy2Cl2 in presence of solvent were stirred at the room temperature for 45 min.
a All the products were confirmed by 1H NMR, IR, and mass spectral data.
b Isolated yields after purification.
a All the products were confirmed by 1H NMR, IR, and mass spectral data and compared with those of authentic samples.
