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.
