  The photolysis of acetone in the presence of various compounds has been investigated between 70°C and °C. If the reaction CH3+CH3=C2H6 has no activation energy, then the activation energies in kcal for the reactions of the type CH3+RH=CH4+R are cyclopropane , cyclobutane , cyclopentane , cyclohexane , benzene , toluene Cited by: Rate data for the abstraction reactions between methyl radicals and some alkanes viz. 2,2-dimethyl­ propane, 2,2,3,3-tetramethylbutane, cyclohexane, butane and 2-methylpropane (containing primary, secondary and tertiary C - H bonds) have Cited by: 1. From the photolysis of acetone in the presence of the nitrogen compounds the following Arrhenius parameters have been determined for hydrogen-abstraction reactions of methyl radicals: [graphic omitted] The results are compared with hydrogen-abstraction reactions involving other nitrogen compounds.

An assessment of multireference character in transition states is considered to be an important component in establishing the expected reliability of various electronic structure methods. In the present work, the multireference characters of the transition states and the forming and breaking of bonds for a large set of hydrogen abstraction reactions from phenolic compounds by peroxyl radicals Cited by:

By photolysing azomethane in the presence of the silane the following Arrhenius parameters have been obtained for hydrogen-abstraction reactions of methyl radicals: [graphic omitted] The high reactivities of chlorosilanes in free-radical reactions appear to be due to abnormally high A -factors rather than to low activation energies.
