The regiochemistry of formylation of several activated naphthalenes and benzenes with pyrophosphoryl chloride and N, N-disubstituted formamides is governed by steric demands of the formylating species and the substrate, but electronic factors may dominate in some cases. Increasing the size of the formamide in the formylating reagent is beneficial for controlling regioselectivity.
