Mercury-sensitized photolysis of Me2SiH2 yields in the primary step an Me2HSi radical and an H atom with a quantum yield of one. The Me2HSi radicals undergo a combination reaction [k(2)] as well as two kinds of disproportionate reactions leading to dimethylsilylene [k(3)] and 1-methylsilaethene [k(4)]. The following branching ratios have been determined: k(3)/[k(2) + k(3) + k(4)] = 0.64 ± 0.10 and k(4)/[k(2) + k(3) + k(4)] ≥ 0.007. For Me3Si radicals the branching ratio for disproportionation was also determined and a value of 0.063 was obtained.
