Description
(I) technical field
The invention relates to a novel method for preparing a 2-phenyl-2-propanol compound by selectively oxidizing a cumene compound, belonging to the field of organic chemical industry and fine organic synthesis.
(II) background of the invention
2-phenyl-2-propanol and derivatives thereof are important fine Chemical intermediates and widely applied to the synthesis of fine Chemical products such as medicines, pesticides, dyes, perfumes and the like (WO 2017068412; WO 2015135094; Chemical Engineering Science 2018,177: 391-398; ChemCatchem 2014,6: 555-560). Currently, cumene and its derivatives are mainly used as raw materials for synthesizing 2-phenyl-2-propanol and its derivatives, and oxygen is used as oxidant to prepare the product through oxidation reaction (ACS Sustainable Chemistry & Engineering 2019,7: 7708-. In the oxidation process, the intermediate product 2-phenyl-2-propyl hydroperoxide and the derivatives thereof have good stability and are not easy to convert, so that the target product 2-phenyl-2-propanol and the derivatives thereof have low selectivity. Meanwhile, the safety of the oxidation system is also reduced due to the existence of peroxide with higher concentration in the reaction system. In addition, a large amount of organic solvents and transition metal catalysts which are toxic and harmful to the environment and organisms are also used in the oxidation process of part of the cumene and the derivatives thereof at present, so that the environmental compatibility and the biological compatibility of the reaction process are reduced, and the product transition metal pollution to a certain degree is also caused (Inorganica Chimica Acta 2019,486: 425-. Therefore, under mild conditions, the high-selectivity oxidation of the isopropyl benzene and the derivative thereof is realized by using a reagent and a catalyst with good environmental compatibility and biocompatibility to prepare the 2-phenyl-2-propanol, which has important significance in industrial production and theoretical research and also meets the urgent requirements of the whole society on green, safe and environment-friendly chemical industry at present.
The solid phase ball milling reaction is characterized in that the interaction between interface materials is promoted by the actions of shearing, rubbing, impacting, extruding and the like between two interfaces which move relatively, so as to realize chemical reaction (Green Chemistry 2018,20: 1435-. The solid-phase ball-milling reaction does not need a solvent, the reaction can be carried out at room temperature, the use of toxic and harmful organic solvents is effectively avoided, the materials do not need to be subjected to heat treatment, the energy consumption is low, and the safety coefficient is high. Meanwhile, due to the solid phase ball milling process, mechanical force is directly applied to the reaction mass, often resulting in a product distribution different from that of the liquid phase reaction. Under the urgent social requirements of development environment, society and human body compatibility chemical process, the solid phase ball milling is used for the catalytic oxidation of the cumene and the derivatives thereof, so that the catalytic oxidation of the cumene and the derivatives thereof can be realized at room temperature, the use of toxic and harmful organic solvents can be reduced, and the distribution of oxidation products can be even changed.
In the field of environmental and biocompatible catalysts, the model compound metalloporphyrin of cytochrome P450 is widely Applied to catalytic oxidation of hydrocarbons (ChemSusChem 2019,12: 684-691; Applied Surface Science 2017,402:436-443), especially ferriporphyrin, has good biocompatibility, effectively prevents the oxidation products and downstream products thereof from being polluted by the metal catalyst, and has high catalytic activity and reaction substrates 1/106~1/105The (mol/mol) amount can complete the catalytic conversion, and can also effectively avoid the pollution of the metal catalyst to the oxidation products. Therefore, the invention carries out the catalytic oxidation of the isopropylbenzene and the derivatives thereof by using the metal ferriporphyrin as the catalyst and the t-butyl hydroperoxide, the hydrogen peroxide, the sodium chlorite or the sodium hypochlorite with better environmental compatibility as the oxidant by a solid phase ball milling method, thereby not only realizing the oxidation conversion of the isopropylbenzene and the derivatives thereof under the mild condition, effectively avoiding the use of toxic and harmful organic solvents, but also obviously improving the selectivity of the 2-phenyl-2-propanol and the derivatives thereof, meeting the social requirements of the current green chemical process, the environmental compatibility chemical process and the biological compatibility chemical process, having important application value and theoretical research, and having important application valueMeaning.
