AbstractComplex OsH3Cl(PiPr3)2 (1) reacts with indenyllithium to give OsH(η5-C9H 7)(PiPr3)2 (2), which affords [OsH(η5-C9H7){CH2CH(CH 3)PiPr2}(PiPr3)]OTf (3) by treatment with methyl trifluoromethanesulfonate. In acetonitrile, complex 3 evolves to an equilibrium mixture of the acetonitrile adducts [Os(η5-C9H7)(NCCH3)-(P iPr3)2]OTf (4) and [Os(η5-C 9H7)(NCCH3)2(PiPr 3)]OTf (5). The addition of 2,5-norbornadiene (NBD) to this mixture leads to [Os(η5C9H7)(η4-NBD) (PiPr3)]OTf (6). Complex 2 also reacts with I2 and HBF4, to give [OsHI-(η5-C9H 7)(PiPr3)2]I (7) and [OsH 2(η5-C9H7)(PiPr 3)2]BF4 (8), respectively. © 2005 American Chemical Society.
