Ho Chi Minh City, July , 2016 Trần Minh Dũng 4 ABSTRACT The utilization of linker Benzen-1,4-dicarboxylic acid (H2BDC) and ligand 1,4- diazabicyclo(2.2) octane (DABCO) for the synthesis of Ni2(BDC)2(DABCO) was implemented by solvothermal method.
The structure of this materials were characterized by using several various techniques, including X-ray powder diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), thermogravimetric analysis (TGA), fourier transform infrared spectroscopy (FT-IR), inductively coupled plasma (ICP) analysis, and nitrogen physisorption measurements. The Ni2(BDC)2(DABCO) was used as heterogeneous catalysts for the direct carboxylation of benzyl bromide with CO2. Several essential factors including solvent, temperature, catalyst amount, type of catalysts and the amount of reductant were investigated. In leaching test, the catalyst was facilely separated from the reaction by centrifugation.
The catalyst recyclability was also specifically examined and the reaction could be reused several times without a significant degradation in catalytic activity. The products were confirmed by 1 H NMR and 13C NMR. To the best of our knowledge, there are no previous reports on carboxylation of halides using CO2 under MOFs catalysis. 5 LỜI CAM ĐOAN Tôi xin cam đoan rằng: Số liệu trong luận văn hoàn toàn do tôi thực hiện và chưa từng được sử dụng trong các bài báo, công trình nào khác.

64 13 CHAPTER 1: LITERATURE REVIEW 1.1 The Synthesis of Phenyacetic Acids 1.1 The importance of phenylacetic acids Phenylacetic acid is one of the most important organic chemical materials, widely used in the field of medicine, pesticide, aromatizer and so on. In more details, the interest in these compounds arises from the fact that a large number of complex molecules such as vancomycin, carbenicillin, ibuprofen, diclofenac, lyrica or lipitor, among many other displayed significant biological activities [1]. Especially, lipitor is ranked the first in the top 200 pharmaceutical Products by Worldwide Sales in 2009 [2].1: Significance of Phenylacetic Acids [2] Besides, phenylacetic acids are used as intermediates in synthesis of some outstanding drugs, for instance, Plavix is a potent anti- platelet drug launched in 1997 by Sanofi- Synthelabo [3,4].2: Structure of Plavix (Clopidogrel) 1.2 Conventional synthesis of phenylacetic acids According to M. Mujahid Alam and his partners’ study, phenylacetic acids were synthesized by Willgerodt-Kindler reaction under PTC (Phase Transfer Catalytic) condition [5].1: Synthesis of phenylacetic acids via Willgerodt-Kindler reaction [5] Other studies concentrated on the carbonylation of alkyl halides.
For example, ZuminQiu and co-workers set a carbonylation reaction under milder condition.2: The synthesis of phenylacetic acid in the carbonylation reaction [6] Furthermore, the direct formation of carboxylic acids under a rhodium catalyst was studied in Department of medicinal chemistry in Canada by Andre´ Giroux and co-workers [7].3: The synthesis of phenylacetic acids under rhodium-catalyzed carbonylation conditions [7]. However, the studies above still presented various limitations such as long reaction times, hazardous reaction conditions and difficulty in product isolation and purification. Therefore, there was an intense demand to develop a new and efficient method for the synthesis of biologically active phenylacetic acids under mild and ecofriendly reaction conditions. As a result, a series of studies of carboxylation using CO2 as an inexpensive and environmental-friendly chemical reagent has published by Ruben Martin .4: Ni-Catalyzed Carboxylation of Alkyl Bromides [8] Scheme 1.5: Ni-catalyzed reductive carboxylation of Allyl Esters with CO2 [9] Scheme 1.6: Ni-Catalyzed Carboxylation of C(sp2) − and C(sp3)−O Bonds with CO2 [10] 1.2 Our approach The carboxylation of alkyl halides with CO2 under homogeneous catalyst In 2003, Ruben Martin and his colleagues showed their experiments on Ni- catalyzed direct carboxylation of benzyl halides with CO2.
This research illustrated the development of a user-friendly and operationally simple catalytic protocol without sensitive and expensive metal complexes [11].
