Abstract The major product of the reaction of 2, 4, 6-triphenylpyranyl with (diacetoxy-λ 3- iodanyl) benzene in acetonitrile and acetone was 2, 4, 6-triphenylpyrylium acetate. Analogous reaction in isopropyl alcohol resulted in the formation of methane, carbon dioxide, 1, 3, 5-triphenylpent-2-ene-1, 5-dione, 2-benzoyl-3, 5-diphenylfuran, 1, 3, 5- triphenylpenta-2, 4-dien-1-one, and a small amount of 2, 4, 6-triphenylpyrilium acetate.
