title: Biradical to biradical rearrangement via 1,3-H atom transfer in photocycloisomerizations of 4-pent-4-enylcyclohex-2-enones.
abstract: An unprecedented 'carbonyl-O-assisted' 1,3-H atom transfer from a CH2 group to a primary alkyl radical center in 1,4-biradicals, formed in a crossed addition mode in the photocycloisomerization of 4-pent-4-enylcyclohex-2-enones, is discussed.
