Process for the preparation of isomerically pure 4-methyl acetophenone |
| abstract |
Process for the preparation of isomerically pure 4-methylacetophenone of the formula (I), DOLLAR F1 by reacting p-tolylmagnesium halide in suitable ethers with acetic anhydride at a temperature in the range from -40 ° C. to +10 ° C., followed by a suitable workup of the reaction solution and separation of 4-methyl acetophenone. DOLLAR A The concentration of the Grignard solution used is preferably in the range from 5 to 40% by weight. |
