Abstract
The transients generated in the γ radiolysis of deaerated solutions of benzoyl-1,1,1-trifluoroacetone (BTA) are stabilized at 77 K and studied by their absorption spectra in the glassy matrices of isopropyl alcohol and methanol-11 mol % H2O. The transients identified are BTAenol, BTAketo, BTAH√ ketyl, [BTA2-enolate]unrelax, and [BTA2-enolate]rela x. BTAenol isomerizes to BTAketo, apparently suggesting that anion radical formation stabilizes the keto form. BTA2-enolate undergoes configurational relaxation from an initially unstable to a final stable relaxed configuration. Both BTAenol and BTAketo react with protons produced on γ radiolysis to give BTAH√ ketyl.
