Hydroboration and hydrogenation of an osmium-carbon triple bond: Osmium chemistry of a bis-s-borane

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 hydroborati...
