Abstract: By reaeting substituted heteroeyele tellttronium salts with aldehydes under mild conditions ccrresponding chalcones and alkadienones were obtained. In the presence of dibutyl telluride, 2-bromomethyl-5-nitrofuran condensed easily with aldehydes in THF to afford corresponding olefin derivatives in one-pot reaction.

Key words: heterocyclic, chalcone, alkadienone, telluronium salt, dibutyl telluride, bromomethyl-nitrofuran
