A phosphorus-containing novel heterocyclic compound, trans-3,5-bis(2,4,6-tri-t-butylphenyl)-1,2,3,5-dithiadiphospholane 3,5-disulfide (trans-1), was isolated in the reaction of 1,3-bis(2,4,6-tri-t-butylphenyl)-1,3-diphosphaallene with sulfur and the structure of trans-1 was confirmed by the X-ray crystallography.Desulfurization of trans-1 afforded the corresponding trans-1,2,4-thiadiphosphetane 2,4-disulfide.
