Article abstract of DOI:10.1007/BF00472538

Norbornadiene derivatives of pyrylium salts were obtained for the first time by <4+2> cycloaddition of cyclopentadienes and 2,6-diaryl-4-phenylethynylpyrylium salts with and without methyl groups in the 3 and 5 positions.Their photochemical transformations were studied.
