    摘要: A process for methylating an alpha carbon adjacent to an electron withdrawing group includes reacting dimethyl ether with a molecule containing the alpha carbon and the electron withdrawing group to substitute a methyl group on the alpha carbon. The process can be conducted in a vapor phase and can be represented by Equation I: R(CH2)nCH2-EWG+CH3OCH3→R(CH2)nCH(CH3)-EWG+CH3OH  (I) where EWG is the electron withdrawing group, and R is H when n is 0, 1 or 2, and R is alkyl, EWG or aryl when n>2. For example, the molecule reacted with dimethyl ether can be acetic acid, propionic acid, methyl acetate, methyl propionate, acetonitrile, propionitrile and acetone. The process is catalyzed by an acid catalyst containing a Lewis acid functionality. When the electron withdrawing group is an acid, a methyl ester can be formed by esterifying the electron withdrawing group with methanol liberated from dimethyl ether. When the process is conducted in the presence of an oxidant, such as oxygen, an &agr;,&bgr;-unsaturated bond can be formed in the molecule according to Equation II: R(CH2)nCH(CH3)-EWG+½O2→R(CH2)nC(═CH2)-EWG+H2O  (II) where EWG is the electron withdrawing group, and R is H when n is 0, 1 or 2, and R is alkyl, EWG or aryl when n>2.

    摘要翻译: 用于甲基化与吸电子基团相邻的α碳的方法包括使二甲醚与含有α碳和吸电子基团的分子反应以取代α碳上的甲基。 该方法可以在气相中进行,并且可以由式I表示:其中EWG是吸电子基团,当n是0,1或2时R是H,当n> 2时R是烷基,EWG或芳基 。 例如,与二甲醚反应的分子可以是乙酸,丙酸,乙酸甲酯,丙酸甲酯,乙腈,丙腈和丙酮。 该方法由含有路易斯酸官能团的酸催化剂催化。 当吸电子基团是酸时,可以通过用从二甲醚中释出的甲醇酯化吸电子基团而形成甲酯。 当该方法在诸如氧的氧化剂存在下进行时,可以根据式II在分子中形成α,β-不饱和键:其中EWG是吸电子基团,当n为0时,R为H ,1或2,当n> 2时,R为烷基,EWG或芳基。
