A cascade of reactions involving anchimeric assistance leads to a highly 'crowded' hexa(alkylcarboxy)benzene.
The substitution of hexabromomethylbenzene with 1-adamantyl carboxylate quantitatively leads to the corresponding hexacyl derivative via anchimeric assistance by the alkylcarboxy substituents.
