W filament to form ethene and 1,1‐dimethylsilene is a catalytic process. In addition, two other decomposition channels exist to produce methylradicals via the SiCH3 bond cleavage and to form propene (or cyclopropane)/dimethylsilylene. It has been demonstrated that both the formation of ethene and that of propene are stepwise processes initiated by the cleavage of a ring CC bond and a ring SiC bond

New experiments on thermally-generated Me2i are interpreted in terms of a reversible silanediyl ⇌ sila-olefin isomerization, as predicted theoretically; earlier apparently conflicting results are shown to be consistent with this explanation.
