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).2015http://zaguan.unizar.es/record/6063210.1021/om501274xhttp://zaguan.unizar.es/record/60632oai:zaguan.unizar.es:60632info:eu-repo/grantAgreement/ES/DGA/E35info:eu-repo/grantAgreement/ES/MINECO/CTQ2011-23459info:eu-repo/grantAgreement/ES/MINECO/CTQ2013-44303-Pinfo:eu-repo/grantAgreement/ES/MINECO/CTQ2014-51912-REDCOrganometallics 34, 3 (2015), 547-550All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/openAccess
