Abstract

The exchange of Si-Me groups caused by silylene ligand rotation in alkoxy-bridged bis(silylene)complexes Cp*(Me₃P)Ru{SiMe₂...O(R)...SiMe₂} (R = Me, ^tBu) is observed by the variable temperature ¹H NMR (VT ¹H NMR) spectroscopy. This fluxionality is considered to be due to the weakened Si...O partial bonds caused by the strong electron-releasing effect of Cp* and PMe₃ ligands.
