Abstract
It was established that homologs of orthoformic ester (orthoacetic and orthopropionic esters), in contrast to it, do not undergo reaction with substituted acetophenones and boron trifluoride etherate to give γ-alkylpyrylium salts; the products obtained are 2,4,6-triarylpyrylium tetrafluoroborates.
