Abstract

The radical cations of the trimethylsilyl esters of acetic and trifluoroacetic acids have been observed by ESR spectroscopy following the γ-irradiation of dilute frozen solutions of the respective esters in CFCl3 at 77 K. The results show that the unpaired electron is largely confined to the Me3Si group in both cations. On annealing to the matrix softening point, intramolecular proton transfer occurs, to give the rearranged cations RC(= O+H)OSiMe2CAH2.
