The Hydrogen-bond as a Configurational Lock in the Photocyclisation of Dibenzoylmethane o-Halogenoanils: Wavelength Dependence of This Reaction
Grimshaw, James,Silva, A. Prasanna de
, p. 301 - 302 (1980)
The tautomers (1, X = Cl, Br, or I) of anils photocyclise to the phenanthridine derivative (2) with varying efficiencies depending on the halogen and the solvent; owing to the low energies of the first excited states the quantum yields vary with irradiation wavelength.
Photocyclization of Aryl Halides. Part 2. The Upper Excited State Reactivity of 3-(2-Halogenoanilino)-1,3-diphenylprop-2-enones; Hydrogen-bonded Configurational Lock in Photosynthesis
Grimshaw, James,de Silva, A. Prasanna
, p. 1010 - 1014 (2007/10/02)
Photocyclization of the internally hidrogen-bonded dibenzoylmethane 2-bromo- and 2-iodo-anils proceed cleanly, though with low quantum yield, to afford a phenanthridine derivative directly and with very little competition from hydrogen abstraction reactio
