  名称：

  A dynamic NMR study of sulphur inversion in transition metal complexes of 2,6-dithiaspiro[3.3]heptane (2,6-DTSH), 2,6-DTSH-2-oxide and 2,6-DTSH-2,2-dioxide

  摘要：

  The following complexes were synthesised [W(CO)(5)L-1], [{W(CO)(5)}(2)L-1], [W(CO)(5)L-2], [W(CO)(5)L-3], [{PdCl2(PPh3)}(2)L-1], [PdCl2(PPh3)L-2] and [PdCl2(PPh3)L-3] where L-1=2,6-dithiaspiro[3.3]heptane (2,6-DTSH), L-2=2,6-DTSH-2-oxide and L-3=2,6-DTSH-2,2'-dioxide. In solution these complexes exhibit pyramidal inversion of the metal-coordinated sulphur atom(s), rates and activation energies of which were evaluated by total NMR bandshape analysis. Delta G double dagger values were in the range 45-50 kJ mol(-1). These magnitudes are discussed in terms of ring geometry distortions and sulphur lone pair interactions.
