The reaction of the phenylselanyl radical with hexabutyldistannane was studied by flash photolysis and the rate constants and activation parameters were determined.

Rate constants for the title reactions have been measured over a range of temperatures by using laser flash photolytic techniques. At 300 K the rate constants are 10.8, 2.01, 2.34, 1.35, 2.47, and 1.84 × 106 M-1 s-1 for methyl, ethyl, n-butyl, isopropyl, cyclohexyl, and tert-butyl, respectively. The Arrhenius preexponential factors range from 109.39 M-1 s-1 for methyl to 108.43 M-1 s-1 for tert-butyl and activation energies from 3.97 kcal/mol for cyclohexyl to 2.95 kcal/mol for tert-butyl. The rate constant (k10) for the 1,5-cyclization of 5-hexenyl radical to cyclopentylmethyl radical can be represented by log k10/s-1 = (10.37 ± 0.32) - (6.85 ± 0.42)/θ, where θ = 2.3RT kcal/mol.
