Abstract: 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.
