Universidad de Zaragoza Hydroboration and hydrogenation of an osmium-carbon triple bond: Osmium chemistry of a bis-s-borane 2015 Access copy available to the general public Unrestricted 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). info:eu-repo/grantAgreement/ES/DGA/E35 info:eu-repo/grantAgreement/ES/MINECO/CTQ2011-23459 info:eu-repo/grantAgreement/ES/MINECO/CTQ2013-44303-P info:eu-repo/grantAgreement/ES/MINECO/CTQ2014-51912-REDC info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 4.186 2015 CHEMISTRY, ORGANIC 12 / 59 = 0.203 2015 Q1 T1 CHEMISTRY, INORGANIC & NUCLEAR 9 / 46 = 0.196 2015 Q1 T1 1.923 2015 Inorganic Chemistry 2015 Q1 Physical and Theoretical Chemistry 2015 Q1 Organic Chemistry 2015 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0001-7620-9618 Cardo, J.J.F.
