G. Olovsson et al., NOVEL DIFFERENCES BETWEEN THE SOLID-STATE AND SOLUTION-PHASE PHOTOCHEMISTRY OF 1,2-CYCLODECANEDIONE, Tetrahedron letters, 38(37), 1997, pp. 6549-6552
1,2-Cyclodecanedione (1) undergoes a novel photorearrangement in the c
rystalline state that is different from the Norrish/Yang type II photo
cyclization process observed in solution. A possible mechanism is pres
ented and discussed. (C) 1997 Elsevier Science Ltd.
