METHOD FOR PRODUCING DI-4,5-[4-(1-METHYL-1-PHENYLETHYL)PHENOXY]PHTHALONITRILE Russian patent published in 2021 - IPC C07C253/30 C07C255/54 

Abstract RU 2755791 C1

FIELD: chemical industry.

SUBSTANCE: invention relates to the chemical industry, in particular to a method for producing di-4,5-[4-(1-methyl-1-phenylethyl)phenoxy]phthalonitrile, which can be used as a starting compound for the synthesis of various metal complexes. The method consists in the interaction of 4-bromo-5-nitrophthalonitrile with 4-cumylphenol in the presence of potash. The interaction is carried out in anhydrous DMF medium and 2 ml of triethylamine for 7.5-8.0 h at 65-70°C. After that, the target product is isolated by pouring into water, then the precipitated precipitate is collected on a filter, washed with 2-propanol, then with water until the pronounced smell of 2-propanol disappears, and dried in an oven at 75-80°C.

EFFECT: the method allows increasing the yield of di-4,5-[4-(1-methyl-1-phenylethyl)phenoxy]phthalonitrile and reducing the duration of the synthesis.
