The photolysis of tetramethylsilane at the long wavelength side of the absorption spectrum gives rise to two main primary photochemical processes: A simple SiC bond‐breaking process with a quantum yield of 0.55 ± 0.17 and a methane elimination reaction with a quantum yield of 0.22 ± 0.07. The radicals disappear by recombination and addition reactions to dimethylsilaethylene. Only an upper limit for the ratio of disproportionation to recombination of 0.13 for the trimethylsilyl radicals can be given. Beside the radical addition reaction dimethylsilaethylene also dimerizes. A semiquantitative evaluation of the data shows that the radical addition reaction as well as the dimerisation reaction proceed with a negligible activation energy.
