PHENYL RADICAL KINETICS.
Scaiano,Stewart

The reactions of phenyl radicals with 17 substrates have been examined by using laser flash photolysis techniques. Absolute rate constants were determined for all the reactions in Freon 113 at 298 K by using iodobenzene or benzoyl peroxide as radical precursors. The following are some representative rate constants, which include all possible modes (or sites) of attack on each substrate: benzene, (4. 5 plus or minus 0. 3) multiplied by 10**5 M** minus **1 s** minus **1; chlorobenzene, (1. 18 plus or minus 0. 13) multiplied by 10**6 M** minus **1 s** minus **1; methyl methacrylate, (1. 8 plus or minus 0. 3) multiplied by 10**8 M** minus **1 s** minus **1; carbon tetrachloride, (7,8 plus or minus 0. 7) multiplied by 10**6 M** minus **1 s** minus **1; tetrahydrofuran, (4. 8 plus or minus 0. 6) multiplied by 10**6 M** minus **1 s** minus **1; toluene (1. 7 plus or minus 0. 7) multiplied by 10**6 M** minus **1 s** minus **1.
IDENTIFICATION OF THE PHENYLCYCLOHEXADIENYL RADICAL IN THE IRRADIATED BENZENE CRYSTAL.
Nakayama,Sheng
, p. 175 - 180 (1980)
In an irradiated benzene crystal, new absorption lines were observed on the low energy side in addition to the usual lines due to the cyclohexadienyl radical. These lines were attributed to the phenylcyclohexadienyl radical arising from the addition of the phenyl radical to a benzene molecule in the solid lattice. The isolated radical is quite stable for laser fluorescence and excitation studies. The deuterium shifts of the lowest electronic transition for a number of the cyclohexadienyl radicals are presented. A method of using the magnitude of the deuterium shift to estimate the size of the radical is proposed.
