4-氟苯腈和2,5-二叔丁基对苯二酚亲核取代反应合成2,5-二叔丁基-1,4-二(对苯腈氧基)苯(产率87.00%,白色晶体,mp 280 ℃),将二腈在碱性条件下水解,合成了分子中同时含有2个醚键和2个叔丁基的芳香族二酸--2,5-二叔丁基-1,4-二(对苯甲酸氧基)苯(产率72.78%,白色针状晶体,mp＞340 ℃). 产物经元素分析和IR、~1H NMR、~(13)C NMR和MS波谱表征确证.
2,5-Di-tert-butyl 1,4-di-(p-phenylene nitriles oxyl) benzene was synthesized via nucleophilic substitution reaction of 4-fluorobenzonitrile with 2,5-di-tert-butyl-p-dihydroxybenzene(yield 87.00%, white crystals, mp 280 ℃). Then 2,5-di-tert-butyl-1,4-di-(p-benzoic acid oxyl) benzene with two ether bonds and two tert-butyls was obtained by alkaline hydrolysis of 2,5-di-tert-butyl 1,4-di-(p-phenylene nitriles oxyl) benzene(yield 72.78%, white acicular crystals, mp＞340 ℃). The chemical structure of this product was confirmed by means of elemental analysis, IR, ~1H NMR, ~(13)C NMR and MS.
