Synthesis and Characterization of New Azo Compounds Linked to 1, 8-Naphthalimide and Studying Their Ability as Acid-Base Indicators

Abstract: New Azo compounds containing an 1,8-naphthalimide moiety were synthesized from 1, 8-naphthalic anhydride by a reaction with p-phenylenediamine or benzidine to produce 1,8-naphthalimide derivatives (1 or 2), which were converted to diazonium salt derivatives by using sodium nitrite and acetic acid at 0-5 áµ’C. The diazonium salt was subjected to a coupling reaction with different substituted phenol in alkaline media at 0-5 áµ’c to produce azo compound derivatives (3-14). The New Azo compound derivatives (… Show more

“…A mixture of 3,3'-dimethyl-[1,1'-biphenyl]-4,4'-diamine (2.12 g, 10 mmol) and 4aminoacetophenone (2.7 g, 20 mmol) in ethanol absolute (35 mL) and glacial acetic acid (500 L) was refluxed for 12 hours [18]. When the reflux had reached its completion, the reaction mixture was cooled to room temperature, and the solid-crude material was filtered, washed with ethanol, dried, and then recrystallized from acetone to give the title product 1.…”

“…A solution of compound 1 (2.23 g, 5 mmol) in acetone was added dropwise through a dropping funnel to succinic, phthalic, tetrachlorophthalic, or tetrabromophthalic anhydride (10 mmol) in acetone (20 mL), with stirring and cooling [18]. After the completion of the addition, the reaction mixture was stirred for 2 hours.…”

“…In homocyclic and heterocyclic forms, azo compounds (-N=N-) play a fundamental role in the dye and pigment industries [11,12]. It extensively entered the analytical chemistry fields [13,14], actually into the industrialization of drugs and other medications [15], and LCD color filters [16]. Azo-Schiff base compounds can be synthesized according to the compound's characteristics and reaction conditions in two ways.…”
