Description
The 77Se NMR spectrum has been recorded for the fluxional heterocyclic selenium sulfide 1,2,3,4,5-Se2S5, which has been prepared from the 77Se-enriched [Ti(C5H5)2Se5] (enrichment 94%) and from S2Cl2. The spectrum shows three second-order multiplets at 1087.1, 1025.0, and 978.9 ppm (relative to Me2Se) corresponding to a five-spin [AMM'XX'] system. A simulation enables the complete assignment of all transitions to be made and yields the refined values of all 77Se-77Se coupling constants. The number of NMR signals, their coupling pattern, and the values of the spin-spin coupling constants are consistent with the concept of facile pseudorotation in the seven-membered chalcogen-containing ring molecules. 20 refs., 4 figs., 1 tab
