摘要：

A new heterocyclic compound, 5H,7H-dibenzo[b,g][1,5]selenoxocine (1), has been prepared from the benzylic selenonium salt of 5H,7H-dibenzo[b,g][1,5]diselenocine. Treatment of the selenoxide of 1 with acetylenedicarboxylate gave the stable selenonium ylide (4); the X-ray structure of 4 shows the strong transannular contact between oxygen and selenium atoms.
