The photochemical hydrogen abstraction reaction of pyrene-4, 5-dione (3) has been investigated by laser flash photolysis. Excitation (λ= 355nm) of a degassed solution of 3 in …
Dihydrodioxin compounds are formed upon visible light irradiation of a mixture of an ortho- quinone and a substituted alkene. The reverse photochemical reaction can result in the …
