Application Of The Solid Acids In Organic Reactions

In recent years, environmental problem has drawn increasing attention. Solid acid catalyst instead of liquid acid is one of the most important ways with the direction of the development of green chemistry.This thesis mainly studied on the solid acid cataysts such as acidic cation exchange resins NKC-9 and Amberlyst-15, using them for the development of the new methods of organic reactions. Then we proposed some new and efficient catalysts in synthesis the compounds of bisphenols, benzoxanthenes and diaminotriphenylmethanes (DTMs), which were confirmed by X-ray analysis, 1H NMR, 13C NMR and HRMS spectra. Based on these reactions, we discussed the reaction mechanism for the synthesis of these compounds and provided a more effective new catalytic system. In addition, the application of solid acids conducted a preliminary study on the classic organic reactions such as Friedel-Crafts alkylation and hydroamination, and achieved the desired results, giving a new approach to the study of these classic organic reactions.
