Abstract

Methyl bromide and ethyl bromide have been used as electron scavengers in tetrahydrofuran and the yields of methane and ethane, respectively, have been treated by the Warman-Asmus-Schuler scavenging equation. This treatment indicates that Gesc = 0.337 ± 0.017 and Ggi = 3.69 ± 0.35. The data for methyl bromide solutions at low concentrations was also found to be compatible with the scavenging equation involving [solute]0.6 recently proposed by van den Ende et al(20). Use of the c0.6 extrapolation yields Gesc = 0.38 ± 0.02. The effect of carbon tetrachloride, triphenylmethyl chloride and biphenyl on the yields of methane from methyl bromide solutions was investigated and the efficiencies of these solutes as electron scavengers relative to methyl bromide are estimated. These relative efficiencies differ from those determined from the rate constants for the reaction of e- s with the solutes. In the case of biphenyl it is proposed that electron transfer from biphenyl radical anion to methyl bromide may account for the discrepancy.
