Si-N bond hydrolysis furnishes a planar 4-coordinate 14-electron Ru(II) complex with a triplet ground state.


Reaction of stoichiometric (2:1) water with [(tBu2PCH2SiMe2)2N]Ru(OSO2CF3) produces planar, 14-valence-electron spin triplet trans-Ru(tBu2PCH2SiMe2O)2. A possible mechanism for this hydrolysis is discussed. This molecule reacts rapidly with CO to give a monocarbonyl, then a cis-dicarbonyl. Reaction with HCCR (R = H or Ph) yields the vinylidene… (More)
