Abstract
The radiolysis of deoxygenated triethylsilane (Et3SiH) was studied in the presence of various concentrations of ethylbromide (EtBr) as a function of the radiation dose. Chain reactions are leading to rather high yields of Br-containing final products, e. g. using 0.93 mol/dm3 EtBr we obtained: Gi(Et3SiBr) = 138, Gi(HBr) = 40, Gi(Br2) = 15 and Gi(Et3Si–SiEt3) = 6, in addition to small amounts of unidentified oligomers. Based on the knowledge from previous steady-state and pulse radiolysis studies of Et3SiH, a probable reaction mechanism is postulated to allow explanation of the present results.
