资源简介：
The complex [OsHCl(CPh)(IPr)(PiPr3)]OTf (1; IPr
= 1,3-bis(2,6-diisopropylphenyl)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-σ-borane complex
OsH2(η2:η2-H2BCH2Ph)(IPr)(PiPr3) (3), whereas pinacolborane (HBPin) affords the arene
compound [Os(η6-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(η6-C6H5CH3)H(IPr)(PiPr3)]OTf (5).
