The complex cis- or trans- reacts with PdCl2 or to give which in turn undergoes MeCN insertion to give cis-2>n>.The latter undergoes cleavage of the chloro-bridges by neutral ligands t-py (py=pyridine), PPh3, and SC4H8> affording dimeric complexes . .> The polymer also reacts with Tl(acac) (acac=acetylacetonate) or Ag(O2CMe) affording the corresponding imidoyl-bridged dimers.The (1)H n.m.r. spectra show a mixture of two isomers for L=py, 4Me-py, and 4But-py; the four (19)F n.m.r. spectra recorded reveal restricted rotation for the C6F5 group.The bridging location of the imidoyl groups has been ascertained by a single-crystal X-ray structure determination of the complex with L=SC4H8 (tetrahydrothiophen), which crystallizes in the monoclinic space group P21/c, with unit-cell dimensions a=9.304(2), b=9.563(2), c=34.979(5) Angstoem, β=95.76(2) degree, and Z=4.The structure was solved by the heavy-atom method and refined to R=0.040 for 3978 observed reflections.
