【摘要】 CuI/2-(2,6-二甲基苯胺基)-2-氧代乙酸作为一个高效的催化体系被成功用于芳基溴代物的羟基化反应.在此催化体系下,催化剂用量降至2 mol%,可用于合成各类取代苯酚.通过调整反应条件,该催化体系还可用于促进芳香溴代物一锅法合成对称的芳香醚.更多还原

【Abstract】 CuI/2-(2,6-dimethylphenylamino)-2-oxoacetic acid(DMPAO) as an efficient catalytic combination was used for the hydroxylation of aryl bromides.The catalyst loading is low to 2 mol% and substituted phenols could be prepared in wide assembly.In addition,by modifying the mixed solvent and base the symmetrical diaryl ethers could be synthesized conveniently from aryl bromides.更多还原
