High-valent oxo-iron(IV) species are commonly proposed as the key intermediates in the catalytic mechanisms of iron enzymes. Water-soluble iron(III) tetrakis-5,10,15,20-(N-methyl-4-pyridyl)porphyrin (Fe(III)TMPyP) has been used as a model of heme-enzyme to catalyse the hydrogen peroxide (H 2 O 2 ) o
## Abstract The Hg(6^3^__P__~1~) photosensitized decompositions of 3‐methyl‐1‐butene, 2‐methyl‐2‐butene, 3,3‐dimethyl‐1‐butene, and 2,3‐dimethyl‐1‐butene have been used to generate 1‐methylallyl, 1,2‐dimethylallyl, 1,1‐dimethylallyl, and 1,1,2‐trimethylallyl radicals in the gas phase at 24 ± 1°C. F
Hot photochemically produced methyl radicals react with (RH) in two ways: by hydrogen abstraction to produce CH4 and by hydrogen replacement to produce R\*CH3. Hot methyl radicals were produced by the ,.,2'78 .: ; I. ',
The reactions of methyl radicals with CC14 and CC13Br have been reinvestigated in the gas phase over a wide range of temperatures and pressures using both the photolysis of acetone and the pyrolysis of di-tertiary butyl peroxide (dtBP) as the methyl radical sources. The results are in essential agre
