P-Methyl acetophenone

The reaction of p-methyl acetophenone and morpholine with elemental sulfur in quinoline (solvent) was studied. [19] The objective was to determine which experimental variables have a significant influence on the yield.

The oxidation of methyl ketones to a-keto carboxylic acids is rare and is accomplished by treatment with a cold solution of potassium permanganate. However, the reaction is not general acetophenone, p-methyl-acetophenone, and 3,4-dimethylacetophenone are oxidized all the way to the corresponding benzoic acids. On the other hand, 2,4-dimethylaceto-phenone, when shaken with approximately 1% aqueous potassium permanganate at room temperature, gives 6 72% yields of 2,4-dimethyl-phenylglyoxylic acid [555, 559],...

The complexation of p-methyl acetophenone 1 with various metal halides has been determined using infrared by monitoring the change in vibration intensity (CO) at 1683 m 1 (Table 3). 

For example, Friedel-Crafts acetylation of toluene (AcCl/AlCls, ethylene dichloride, rt) affords p-methyl-acetophenone predominantly (p m o = 97.6 1.3 1.2 eq 1). ...
