Popis: Whereas benzoylation of toluene or m-xylene is known to lead to a mixture of 2- and 4-methylbenzophenone and to 2,4-dimethylbenzophenone respectively, the presence of a blocking t.butyl group in the 4- and the 5-positions respectively leads to products which on debutylation yield benzophenones with substituents in the ortho position only.
