| Abstract: | Contrary to the classical silylene dimerization leading to a disilene structure, phosphine stabilized hydro‐ and chloro‐silylenes ( 2 a , b ) undergo an unique dimerization via silylene insertion into Si? X σ‐bonds (X=H, Cl), which is reversible at room temperature. DFT calculations indicate that the insertion reaction proceeds in one step in a concerted manner. |
