I wanted to use Titanium (IV) chloride first, but it was explosive with basic solutions. Then I tried Titanium (IV) tert-butoxide. Reaction was held in octanol. I used 50 mg of Sodium Methoxide and 50 mg of strarting phthalonitrile compound. But reaction did not occur. I attached 10 different metals to phthalocyanine core like this, but I can't attach titanium.

I think, no need to use Na-methylate. Instead use DBU in boiling octanol.
You can firstly synthesis metal-free phthalocyanine(finished the reaction and purify) then you put another reaction with metal-free pc and the titanium tetrabutoxide, finally you can obtain titanium phthalocyanine.
