Abstract
Способ получения замещенных 4-нитро-5-(2-оксоэтил)-фталонитрилов общей формулы ! ! где a R=4-Me-C6H4; b R=4-MeO-C6H4; c R=2-thienyl, ! заключающийся в том, что в качестве исходных реагентов для синтеза замещенных 4-нитро-5-(2-оксоэтил)фталонитрилов используют 4-бром-5-нитрофталонитрил и натриевые соли производных 2,4-диоксобутановых кислот, взаимодействие указанных реагентов протекает при температуре 18…35°C и мольном соотношении 1:2 соответственно в течение 18-24 ч в растворе диметилформамида, затем реакционную массу разбавляют десятикратным избытком 5%-ного раствора соляной кислоты, выпавший кристаллический осадок отфильтровывают и перекристаллизовывают из спирта. The method of obtaining substituted 4-nitro-5- (2-oxoethyl) -phthalonitriles of the general formula! ! where a R = 4-Me-C6H4; b R = 4-MeO-C6H4; c R = 2-thienyl,! consisting in the fact that as the starting reagents for the synthesis of substituted 4-nitro-5- (2-oxoethyl) phthalonitriles, 4-bromo-5-nitrophthalonitrile and sodium salts of derivatives of 2,4-dioxobutanoic acids are used, the interaction of these reagents proceeds at a temperature of 18 ... 35 ° C and a molar ratio of 1: 2 for 18-24 hours, respectively, in a solution of dimethylformamide, then the reaction mass is diluted with a ten-fold excess of a 5% hydrochloric acid solution, the precipitated crystalline precipitate is filtered off and recrystallized from alcohol.
