Versuchsvorschrift
That is, α,α,α',α'-tetrabromo-o-xylene [the formula (V)] in an amount of 0.1 mol and fumaronitrile in an amount of 0.178 mol are reacted at 75° C. for 7 hours in the presence of 0.67 mol of sodium iodide in anhydrous N,N-dimethylformamide to yield 2,3-dicyanonaphthalene of the formula (VI). Subsequently, 57.3 mmol of the 2,3-dicyanonaphthalene is reacted with ammonia in the presence of sodium methoxide in methanol with heating for 3 hours to yield 1,3-diiminobenzo(f)isoindoline of the formula (VII). Further, 30.6 mmol of the 1,3-diiminobenzo(f)isoindoline was reacted with 47.1 mmol of silicon tetrachloride in anhydrous tetralin and anhydrous tri-n-butyl-amine under reflux for about 3 hours to give dichlorosilicon naphthalocyanine [SiNoX2 (X=Cl)] which can be represented by the formula (II) except that the two OHs are replaced by two Cl's. Then, this compound is treated with concentrated sulfuric acid and then concentrated ammonia water to give dihydroxysilicon naphthalocyanine [SiNcX2 (X=OH)] of the formula (II).
