The Friedel-Crafts ketone synthesis has been applied to but few s-alkylbenzenes; there are no reports of such reactions with p-di-s-alkyl derivatives. Since the latter are sterically hindered with respect to the available ortho positions, have tertiary hydrogen in the side chains, which also are susceptible to rearrangement, migration and displacement in the presence of aluminum chloride, it was thought of interest to study the course of their ...
