Abstract

The preparation of m-trifluoromethylbenzalde-hyde from the bromo Grignard reagent and N- methylformanilide has been described. l3 Our yield of 38y0 of pure aldehyde however, was considerably lower than the 52--59y0 previously reported. 13 It should be mentioned that autoxidation of this aldehyde to m-trifluoromethylbenzoic acid occurred within several hours at room temperature, so that the reaction with aceturic acid to form 2-methyl-4-(m- ...
