Deselenation of a cyclic polyselenide mixture, Tbt(s)CHSe(n) 5, resulted in the formation of Tbt(s)CHSe 3a, which gave its head-to-tail dimer 12 upon concentration of the reaction solution although it was stable in a dilute solution. Thermolysis of 12 gave an equilibrium mixture of 12, 3a, and its rotational isomer Tbt(a)CHSe 3b, and 3b was isolated as a solid stable even in air. Reaction of 3a and 3b with W(CO)5. THF gave the corresponding η1-selenoaldehyde tungsten complexes 4a and 4b, respectively. Some reactions of 4a were carried out to give products accompanied by decomplexation.

A novel cyclic polysulfide, octathionane TbtCHS8 (7; Tbt=2,4,6-trisphenyl) was synthesized by thermal reaction of the corresponding diazomethane TbtCHN2 with cyclooctasulfur (S8) in benzene in the dark.Molecular structure of 7 was determined by X-ray crystallographic analysis and the geometry of the C8 ring was compared with that of theoretically optimized cyclononanosulfur (S9).Desulfuration of 7 by triphenylphosphine afforded the corresponding pentathiane TbtCHS5.

Thermal reaction of a sterically bulky diazomethane with elemental sulfur in benzene afforded a novel cyclic polysulfide, 1,2,3,4,5,6,7,8-octathionane (1).Molecular structure of 1 was determined by X-ray crystallographic analysis and the geometry of its C
