4-Hydroxypyrylium cations undergo photo-ring contraction upon irradiation of 50 percent H~SOI,. Dihydroxycyclopentenones are intermediates in these reactions. A variety of 4-hydroxypyrylium cations are known to undergo photoisomerization in concentrated H~SOI, to yield 2-hydroxypyrylium cations. la
