THE WAVELENGTH- AND SOLVENT-DEPENDENT PHOTOCHEMISTRY OF 1,1-DICYANO-2-METHYL-4-PHENYLBUT-1-ENE; REACTION FROM TWO EXCITED STATES

1,1-Dicyano-2-methyl-4-phenylbut-1-ene ( 4 ), on u.v. irradiation in solution, yields two products, 3,3-dicyano-2-methyl-4-phenylbut-1-ene ( 5 ) and 1-dicyanomethyl-1-methylindane ( 6 ).The photoreaction is dependent both on solvent polarity and on the excitation wavelength.A long-wavelength band in the absorption spectrum of ( 4 ), not present in the spectra of its isolated chromophores, is attributed to an intramolecular charge-transfer interaction.THe unusual dependence on solvent and wavelength is explained in terms of a reaction mechanism in which ( 5 ) is formed from a delocalised excited state, with a staggered conformation, and ( 6 ) from a charge-transfer excited state, with an eclipsed conformation.
