Abstract

The 2,6-di-t-butyl-4-methylphenoxo ligand (ArO-) is ambidentate, giving rise to the O-bonded 15-electron d1 [Ti(η-C5H5)2OAr] and the η5 -[C(2)-C(6)]-bonded 18-electron d8 complex [Rh(ArO-η5)(PPh3)2], obtained from [{Ti(η-C5H5)2Cl}2]-LiO Ar and [Rh{N(SiMe3)2}(PPh3)2]-ArOH, respectively; the average TiC(η) distance is 2.362(10) Å, TiO 1.892(2) Å, and O:C(of Ar) 1.352(3) Å, and TiOC 142.3(2)°; in the RhI complex, C(2)C(6) are coplanar (with CC(av.) 1.38(2) Å). C(1)O 1.28 Å, and Rh to C(2) C(6) bond lengthsare in the range 2.19-2.65 Å.
