Syn and anti 2H>allyl radicals are generated from deuterated allyl phosphites by attack of tert-butoxy radicals, and their interconversion is studied in the temperature range of 50-100 deg C.Steady-state kinetic analysis together with time-resolved measurements of the diffusion-controlled recombination kinetics yield an allyl rotational barrier of 15.7 +/- 1.0 kcal/mol (logA = 13.5 +/- 0.5).From this a value of 14.0-14.5 kcal/mol is deduced for the allyl delocalization energy.
