TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation: No preparation method is given. Preferred Components: In (I): at least one of the linkage group is substituted or at least two linkage groups are connected to each other. (I) is substituted metal containing complex compounds of formula (II), (III), (IV) or (V). EXAMPLE - Resorcinol (110 mmol), 2-bromopyridine (100 mmol), 1-methylimidazole (5 mmol) and potassium carbonate (200 mmol), pyridine (80 ml) were added and bubbled with nitrogen for 20 minutes before copper(I) iodide (10 mmol) was added and bubbled for 10 minutes. The vessel was sealed and heated to 140 degrees C. while stirring. After 2 days, the solution was allowed to cool to obtain solids. The solids was filtered, rinsed and worked up to give 3-(pyridin-2-yloxy)phenol (Ia). Then, (Ia), 2,6-dibromopyridine (50 mmol), 1-methylimidazole (25 mmol) and potassium carbonate (100 mmol), toluene (80 ml) were added and bubbled with nitrogen for 20 minutes before copper(I) iodide (5 mmol) was added and the solution bubbled for 10 minutes. The vessel was sealed and heated to 140 degrees C. with stirring. After 2 days, the solution was allowed to cool to obtain solids. The solids was filtered, rinsed and worked up to give 2-(3-(3-bromophenoxy)phenoxypyridine (Ib). Copper(I) oxide (1 mmol), syn-2-pyridinealdoxime (4 mmol), 3,5-dimethylpyrazole (12 mmol), cesium carbonate (25 mmol), (Ib) (10 mmol), and anhydrous, degassed acetonitrile (100 ml) were mixed to form a solution. The solution was refluxed for 2 days, allowed to cool to room temperature, diluted, filtered and worked up to give 2-(3-(3-(3,5-dimethyl-1H-pyrazol-1-yl)phenoxy )phenoxy)pyridine (Ic). Potassium tetrachloroplatinate(II) (0.41 mg), (Ic) (1 mmol) and acetic acid (35 ml)were mixed and was refluxed for 3 days to form a mixture. The mixture was allowed to cool to room temperature. The resulting white complex was filtered, washed, dried to give N'-eth-(E)-ylidene-N-((Z)-1-methyl-propenyl)-N-(3-(3-(pyridin-2-yloxy)-phenoxy)-phenyl)-hydrazine platinum complexe (60% yield).
