    Abstract

    Protonation of the N-heterocyclic carbene (NHC) complex Ru(IPr) 2(CO)H(OH) (IPr = l,3-bis(2,6-diisopropy-lphenyl)imidazol-2-ylidene) with HBF4 OEt2 in thf affords the cationic aqua hydride complex [Ru(IPr)2(CO)H(OH2)](BF2), whereas if the solvent is changed to benzene, loss of imidazolium salt and H20 occurs to leave the 12e fragment [Ru(IPr)-(CO)H]+, which is isolated as the cationic arene species [Ru(IPr)(η6- C6H 6)(CO)H](BF6). © 2009 American Chemical Society.
