Formation and reactions of monomeric and dimeric radical cations of aliphatic ketones in freon matrices
- 1. Moskovskij Gosudarstvennyj Univ. (USSR). Khimicheskij Fakul'tet
Description
ESR spectra of γ-irradiated acetone and CH3COEt solutions (0.1-22%) in CFCl3 were studied. The yields of monomer and dimer radical cations of ketones and RCHCOCH3 radicals depend on ketone concentration in CFCl3. When exposed to light the dimeric radical cations are transformed into RCHCOMe, while the monomeric radical cations disappear without further radical production. Different types of solid phase ion-molecular reactions for monomer and dimer radical cations are discussed. (author)
