Reaktionsschritte

A solution of 0.01 moles of tungsten hexachloride in 20 mL tetrahydrofuran (THF) is added to a solution of 0.02 moles of 2-hydroxypyridine and 0.02 moles of triethylamine in 50 mL THF at 0° C. The mixture is stirred while warming to room temperature, then stirred overnight. The mixture is then filtered and the THF evaporated under vacuum. The product is extracted from the residue with toluene and then recovered by evaporating the toluene. A polymer may be prepared by using the catalyst in accordance with the procedure described in Example 4.
