synthesis of cis-and trans-2, 6-diphenyl- 1, 4-diselenafulvenes is described. The process involves the reaction of phenylacetylene with sodium hydroxide and selenium at 45–50°C and under PTC-Untrasound conditions to afford the 1, 4-diselenafulvenes in good to excellent isolated yields. The reaction mechanism is discussed.
