| Title | Reaction of Trimethyl-and Dimethyl-Silyl Radicals with Pentamethyldisilane  | ||
| Abstract | The rate constant for the H atom abstraction of trimethylsilyl radicals from pentamethyldisilane k (4) (&(4)) was measured relative to the trimethylsilyl combination reaction k(3). A value for • ]/k (3) = (8.53±0.08) • 10" 11 cm 3 ' 2 s~ 1/2 was obtained. For the dimethylsilyl radical, a smaller value for the corresponding rate constant ratio (5.9 + 0.2) • 10" 11 cm 3 ' 2 s" 1/2 was measured, and this was attributed to a disproportionation reaction between the dimethylsilyl and the pentamethyldisilyl radical leading to dimethylsilylene. | ||
