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.
