The liquid-phase oxidative carbonylation of aromatics leading to aromatic carboxylic acids is studied to develop new approaches to 2,6-naphthalenedicarboxylic acid (NDA) preparation. It is shown that the catalytic system Pd(OAc)2/K2S2O8 allows the synthesis of naphthalic anhydride (NAn) by direct oxidative carbonylation of naphthalene under mild conditions (25 °С, 2 atm СО). The subsequent alkaline
研究了导致芳族羧酸的芳族化合物的液相氧化羰基化,以开发制备2,6-萘二甲酸(NDA)的新方法。结果表明,催化体系Pd(OAc)2 / K 2 S 2 O 8允许在温和的条件下(25°C,2 atmСО)通过萘的直接氧化羰基化反应合成萘酐(NAn)。已知随后的NAn碱水解和所获得的1,8-萘二羧酸盐的异构化导致NDA。
