Syntheses of octa(dialkylamino)azaphthalocyanines
Nickel(II) octa(4-morpholinyl)- (11a) and copper(II) octa(l-pyrrolidinyl)- (11b) azaphthalocyanines have been prepared from the corresponding pyrazine diiminoimides (10). The precursor pyrazine dicarbonitriles (2) gave 6-cyanopyrazine-5-alkyl carboximidates (3-9) as stable intermediates when reacted with ammonia and catalytic amounts of sodium alkoxide in alcohols. Compounds 3-9 were converted to the diiminoimides 10 upon reflux in propanol or butanol for several hours. This unusual reaction pattern was observed for pyrazine-2,3-dicarbonitriles 2 substituted in the 5- and B-positions with morpholine, thiomorpholine, piperidine or pyrrolidine.

Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. A catalyst, therefore, does not appear in the overall stoichiometry of the reaction it catalyzes.I hope my blog about 696-62-8 is helpful to your research. SDS of cas: 696-62-8.
