The behavior of 2-benzopyrylium salts with a CH2 group in the 1 position at pH ⩽ 7 was studied, and it was established that they undergo recyclization to α-naphthols under these conditions. A mechanism for the conversion is proposed. One of the intermediates, viz., 3-hydroxy-1-tetralone, was isolated.
