It can be synthesized starting from cyclooctene, obtained from the 1,3butadiene and 1,5-cyclooctadiene
through a metathesis reaction (see Fig.
In a typical procedure, 0.13 g of tricarbonyl(cyclooctatetraene)iron (> 96%), 0.54 g of dimethyl(1,5-cyclooctadiene
)platinum(II) (99%), 0.57 g of tris(acetylacetonate)iron(III) (99%), and 0.13 g of silver trifluoroacetate (97%) were dissolved in a 0.5 wt% solution of polystyrene-b-poly(4-vinylpyridine) (PS-P4VP, [M.sub.n.sup.ps] = 22 kg [mol.sup.-1], [M.sub.n.sup.P4VP] = 22 kg [mol.sup.-1], and polydispersity index = 1.09) in 45 mL of toluene (>99.5%).
The materials were prepared by reaction of the ligands 1-3 with bis(1,5-cyclooctadiene
) nickel under an argon atmosphere.
This matrix can be synthesized starting from cyclooctene, that can be obtained from the 1,3-butadiene and 1,5-cyclooctadiene
through a metathesis reaction.
