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 [((Bu2PCH2SiMe2)-Bu-t)(2)N]Ru(OSO2CF3) produces planar, 14-valence-electron spin triplet trans-Ru((Bu2PCH2SiMe2O)-Bu-t)(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 ((Bu2PCH2SiMe2O)-Bu-t)(2)Ru=C=CHR.
