A NHCs-mediated benzoates formation was developed by treatment of aromatic aldehydes with alkyl halides in the presence of oxygen. Corresponding benzoate derivatives were obtained in high yields up to 99%. The reaction mechanism was also discussed and a NHCs-mediated O-alkylation and subsequent oxidation process was proposed.
NHCs介导的苯甲酸酯的形成是通过在氧气存在下用烷基卤化物处理芳香醛来实现的。以高达99%的高收率获得了相应的苯甲酸酯衍生物。还讨论了反应机理,并提出了NHCs介导的O-烷基化和随后的氧化过程。
