Kinetics Of

The kinetics of abstraction of hydrogen atoms from the methyl group of the toluene molecule by methyl radicals at 430-540�K have been determined. The methyl radicals were produced by pyrolysis of di-t-butyl peroxide in a stirred-flow system. The kinetics ,agree substantially with those obtained by previous authors using photolytic methods for generating the methyl radicals. At toluene and methyl-radical concentrations of about 5 x 10-7 and 10-11 mole cm-3 respectively the benzyl radicals resulting from the abstraction disappear almost entirely by combination with methyl radicals at the methylenic position. In this respect the benzyl radical behaves differently from the iso-electronic phenoxy radical, which previous work has shown to combine with a methyl radical mainly at ring positions. The investigation illustrates the application of stirred-flow technique to the study of the kinetics of free-radical reactions.

Several 4-substituted benzyl radicals of the general form R(On)SC6H4CH2•(n = 0, 1, 2; R = Me, Ph, Tol, COCH3 OCH3) have been investigated by electron spin resonance (esr) spectroscopy. In general, the ability to delocalize spin density onto the substituent decreases as n increases. The effect of R on the spin density depends on the oxidation state of the sulphur. These trends are explained by considering the sulphur to be either a spin donor or a spin acceptor, depending on the oxidation state. The σ•α values are determined.

Photolysis of dibenzyl ketone in vacuum-dried Nafion membranes leads to the detection of fluorescence from the protonated ketone and formation of modest yields of benzyl cations characterized using laser photolysis techniques. Exchange of the acid sites in Nafion by cationic surfactants leads to decreased environmental polarity and a change in mechanism towards the benzyl radical chemistry which is common in organic solvents. The decay of benzyl radicals in Nafion membranes shows magnetic field dependence which indicates that geminate processes play an important role.
