| Abstract: | Preparation and Structures of Sulfoximino Compounds The crystal and molecular structures of (CH3)2SON]SO2CH3 ( 1 ), (CH3)2SON]2SO2 ( 2 ) and (CH3)2SON]3S+Cl– ( 3 ) are determined. 1 and 3 are prepared by new methods. 1 crystallizes triclinic (P 1) with a = 588.3, b = 768.6, c = 1640.5 pm, α = 89.26°, β = 89,38°, γ = 77,08° and Z = 4. 2 crystallizes monoclinic (C2/c) with a = 2387.2, b = 638.5, c = 2870.9 pm, β = 113,15° and Z = 16. 3 crystallizes orthorhombic (Pca21) with a = 2892.4, b = 1055.6, c = 953.5 pm and Z = 8. The bonds are discussed on the basis of an NBO analysis for 1 and the IR and NMR spectra, resp. |
