Photolyses of 1-alkoxy-9-diazoanthrones 12 in benzene induce abstraction of hydrogen from the side chain, followed by cyclization (---) 15 --~ 16) or disproportionation (--~ 17 + 18) of the intervening biradicals 20. In alcohols, reduction of triplet anthronylidenes (314 ~ 21 ~ 22) competes with the
