D. Armesto et al., A MECHANISTIC STUDY ON THE PHOTOCHEMICAL CYCLIZATION OF PROTONATED 2-AZA-1,3-DIENE DERIVATIVES, Anales de quimica, 91(5-6), 1995, pp. 374-379
Quantum yield determinations for the photocyclization of protonated yl
oxy-3,4-diaryl-1,1-diphenyl-2-azabuta-1,3-dienes 5 into substituted 3-
aryl-1,1-diphenylisoquinolin-4(1H)-ones 6 support the involvement of a
n intramolecular single electron transfer (SET) mechanism from an aryl
group to an iminium system.
