Resumen:
The complex [OsHCl(¿CPh)(IPr)(PiPr3)]OTf (1; IPr = 1,3-bis(2,6-iisopropylphenyl)imidazolylidene, OTf =CF3SO3) replaces the chloride ligand with a hydroxo group to give [OsH(OH)(¿CPh)(IPr)(PiPr3)]OTf (2), which undergoes hydroboration and hydrogenation of its metal-carbon triple bond. The hydroboration products depend upon the reagent used. Treatment of 2 with Na[BH4] leads to the bis-s-borane complex OsH2(¿2:¿2-H2BCH2Ph)(IPr)(PiPr3) (3), whereas pinacolborane (HBPin) affords the arene compound [Os(¿6-C6H5CH2Bpin)H(IPr)(PiPr3)]OTf (4). The hydrogenation of the triple bond of 2 occurs under 4 atm of H2 and yields the toluene derivative [Os(¿6-C6H5CH3)H(IPr)(PiPr3)]OTf (5).
