  Ring opening of 1,3-dithietane-1,1-dioxide by a triosmium cluster

  摘要：

  The reaction of the cyclic sulfone, 1,3-dithietane-1,1-dioxide, 1 with Os-3(CO)(10)(NCMe)(2), 2 at 25 degrees C provided the new compound Os-3(CO)(10)(mu -CH2SCH2SO2), 3 in 73% yield. When solutions of 3 in heptane solvent were heated to reflux, they are converted to the compound Os-2(CO)(6)(mu-CH2SCH2SO2), 4 in 46% yield. Both products were characterized by IR, H-1-NMR and single crystal X-ray diffraction analyses. Compound 3 contains a bridging SCH2SO2CH2 ligand formed by an opening of the ring of the sulfone and one edge of the osmium cluster. Compound 3 was formed by the loss of an Os(CO)(4) group from 3. The SCH2SO2CH2 ligand in 4 is coordinated in a fashion similar to that in 3. In both products, one of the oxygen atoms of the sulfone group is coordinated to one of the osmium atoms. In both cases, the S-O bond distance to the coordinated oxygen atom has increased in length and IR spectra of the S-O stretching absorptions show a substantial weakening of the S-O bond.
