In a C2-symmetric environment such as in structure B (Figure 1, D, or E (Figure 3, two doublets are expected for the diastereotopic hydrogens of the CHH ligand unit adjacent, as well as for the diastereotopic hydrogens of CHHPh groups in dibenzyl complexes 7 and 8. Also, the 'F NMR spectrum would feature two quartets for the nonequivalent C (CF3, CF 3) groups; see refs 4a,b

R1,R2)H led to intractable mixtures of compounds. We assume that the latter difficulties reflect the versatile redox chemistry of Ti, combined with the identified decomposition pathways of dibenzyl-metal (Zr, Hf) complexes of these new ligands. It is noteworthy that, to our knowledge, there is no dibenzyl-titanium complex of "regular" phenoxyimine ligands reported thus far; see refs 8 and 9.

To prevent this decomposition pathway, the use of gem-dimethyl- substituted pro-ligand analogues was attempted. Surprisingly, fluorous (di)imino, di)ols such as HOC (CF3)2CMe2C (iPr)=N (iPr) and [HOC, CF3)2CMe2C (iPr)=NCH2-]2 were found not to react with M (CH 2Ph)4 (M, Ti, Zr, Hf) in toluene up to 60-80 °C, temperatures at which the latter precursors start decomposing at a significant rate. Reasons for this absence of reactivity, while no obvious steric and electronic effects can be accounted for, remain obscure. To date, such gem-dimethyl-substituted pro-ligands could be installed only at aluminum centers, under conditions much more drastic than those used for the parent nonsubstituted pro-ligands; see ref 11

The reactions of Zr (CH2Ph)4 with 1 equiv of {ONMc,Ph)H or {ONph,ph}H were attempted to potentially access the corresponding Zr (CH2Ph)2{ON-R1,R2} complexes. However, in both cases, NMR monitoring showed that these reactions led to ca. 1:1 mixtures of Zr (CH2Ph)4 and Zr (CH 2Ph)2{ONR1,R2}2, which further evolve by decomposition of the latter species into Zr (CH2Ph){ON- R1,R2){ONR1,R2, Those observations indicate that disproportionation of the putative intermediate species [Zr (CH 2Ph)3, ONR1,R2, or consecutive reaction of the latter species with {ONph,ph}H (to form in both cases Zr (CH 2Ph)2{ONR1,R2}2) is faster than abstraction of a hydrogen atom from the ligand backbone

Complexes 1 and 2 were also briefly investigated in polymerization catalysis, although no valuable performance was expected, considering the equatorial coordination of the tetradentate ligand and the anticipated absence of cis vacant sites in the resulting cationic species. As a matter of fact, for instance, when complex 1 was activated with MAO (1000 equiv, toluene solution), no polymerization activity was observed (1 atm ethylene, 25 °C).
