Wu, Jianhong; Chen, Dongyin; Li, Fei published an article in 2016, the title of the article was Synthesis of tert-butyl ethers and tert-butyl esters catalyzed by acid-treated montmorillonite supported zinc chloride.Reference of tert-Butyl 2-(4-nitrophenyl)acetate And the article contains the following content:
With acid-treated montmorillonite supported zinc chloride (H-mont/ZnCl2) as the catalyst, phenols, alcs., and carboxylic acid were reacted with di-tert-Bu bicarbonate to give tert-Bu ether and tert-Bu ester derivatives at 120°C in sealed tube with yields ranging from 61% to 75%, which was simple and environmentally friendly. All the compounds synthesized were confirmed by 1H NMR and ESI-MS. The effects of solvent, temperature, metal ion and some other factors to the reaction were investigated. A possible mechanism for this reaction was proposed. The study provided a new method for this type of synthesis in the future. The experimental process involved the reaction of tert-Butyl 2-(4-nitrophenyl)acetate(cas: 29704-38-9).Reference of tert-Butyl 2-(4-nitrophenyl)acetate
