✦ Synopsis

The participation of a 1,3-hydrogen shift in initially formed secondary alkoxyethyl radicals R 1 R 2 CH-O-CH -CH 3 during their free-radical chain additions to methyl 2,3,3-trifluoroacrylate has been confirmed using a deuterium marked additive. Indirect evidence has been obtained for a partial 1,3-hydrogen shift in secondary radicals CH 3 (CH 2 ) n -CH -O-CH 3 to primary radicals CH 3 (CH 2 ) n -CH 2 -O-CH 2 . Initial formation of tertiary alkoxyethyl radicals R 1 R 2 C -O-CHR 3 R 4 in the propagation step was not observed due to steric factors.
