Abstrakt: The conversion of 2-benzopyrylium salts to benz [a] anthracenes, which proceeds through prior dimerization of a new type, was observed. An intermediate dimer was isolated, its properties were studied, and assumptions regarding the mechanisms of its formation and conversion to benz [a] anthracenes, cenes were expressed.
