Nitration of three types of tetramethylacetophenones and pentamethylacetophenone with fuming nitric acid in acetic anhydride was carried out. The product distributions were compared with those estimated from substituent effects. A variety of acylpentainethylbenzenes including pentamethylbenzoic acid were reacted with the nitrating system to give regioselectively 2-(nitromethyl)-3, 4, 5, 6-tetramethylacylbenzenes. ...
