η2-iminoacyl and η2-acyl monocyclopentadienyl tantalum complexes bearing oxo and oxo-borane ligands

Alkyl-chloro ligand exchange by the reaction of [TaCp*R 2{O·B(C6F5)3}] (R = CH 2Ph, Me) with Ph3CCl gave the monoalkyl compounds [TaCp*RCl{O·B(C6F5)3}] (R = CH2Ph, Me). Insertion of CNAr (Ar = 2,6-Me2C 6H3) and CO into a Ta-C bond of the mono- and dialkyl complexes gave the iminoacyl compounds [TaCp·X{η2-C(R)= NAr}{O·B-(C6F5)3}] (X = R = CH 2Ph, Me; X = Cl, R = CH2Ph) and the acyl compounds [TaCp*X{η2-C(R)=O}{O·B(C6F 5)3}] (X = R = CH2Ph, Me; X = Cl, R = CH 2Ph), respectively. The related chloro compound [TaCp*Cl{η2-C(Me)=NAr}{O·B(C6F5) 3}] was isolated from the reaction of the oxo derivative [TaCp*Cl{η2-C(Me)=NAr}(O)] with the Lewis acid B(C 6F5)3. Addition of CNAr or pyridine to [TaCp*(CH2Ph){η2-C(CH2Ph)=NAr} {O·B(C6F5)3}] afforded the borane-free complex [TaCp*(CH2Ph){η2-C(CH 2Ph)=NAr}(O)] and the acid-base adduct L·B(C6F 5)3 (L = py, CNAr). The molecular structures of [TaCp*Cl{η2-C(Me)=NAr}{O·B(C6F 5)3}] and [TaCp*(CH2Ph) {η2-C(CH2Ph)=O}{O·B(C6F 5)3}] were obtained from X-ray diffraction studies. Wiley-VCH Verlag GmbH & Co. KGaA, 2006.
