Reversible Dimerization of Phosphine-Stabilized Silylenes by Silylene Insertion into Si(II) -H and Si(II) -Cl σ-Bonds at Room Temperature.
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.
