✦ Synopsis

Three kinds of bromides were prepared from the reaction of dialkyl itaconates with bromotrichloromethane as precursors of analogous radicals for the propagating radicals of some dialkyl itaconates, i.e., the methyl, deuterated methyl, and adamantyl ester derivatives. The radicals were generated by photoirradiation of a toluene solution of the bromides in the presence of hexabutylditin at Οͺ60 to 60Β°C, and ESR spectra were recorded. Hyperfine splitting and the temperature dependence of the linewidth were determined. The ␀-deuterated radicals were also characterized to determine a coupling to ␀-hydrogens.

The combination of high-performance liquid chromatography (HPLC) and ESR spectrometry was used to isolate the radical products obtained by photolysis of o-methylbenzaldehyde (l), o-methylacetophenone (2) and omethylbenzophenone (3) in the presence of a-phenyl-N-tert-butylnitrone and its derivatives
