Substitution reactions of dichlorobis(betadiketonato-O,O?) titanium(IV) complexes with aryl diolato ligands: An experimental and computational study
Substitution reactions of complexes Ti(beta-diketonato) 2Cl2, in which the two monodentate Cl- ligands are replaced by different bidentate aryl-diolato ligands (catechol, naphthol, biphenol, binaphthol, or methylenebinaphthol), produce remarkably hydrolytically stable titanium(IV) complexes with 5-, 7- or 8-membered chelating rings. The lability of the chlorine ligand in the parent compound is dependent on the strength of the electron donating properties of the spectator beta-diketonato ligand around the titanium centre. The reactivity of Ti(RCOCHCOR?) 2Cl2 complexes according to the beta-diketonato ligand (RCOCHCOR?)- follows the order (PhCOCHCOPh)- > (PhCOCHCOCH3)- > (CH3COCHCOCH 3)-, in line with results for other known transition metal complexes. Detailed substitution kinetics along with the X-ray crystal structure of a mono-chloride Ti(beta-diketonato)2(Cl)(naphthol) reaction intermediate are reported. DFT calculations on the reaction of Ti(acac)2Cl2 with different aryl-diolato ligands reveal that chlorine substitution proceeds via a two-step interchange mechanism with the formation of two seven-coordinated transition states and one six-coordinated intermediate. The computed mechanism agrees very well with experimental kinetic and X-ray data. . 2013 Elsevier Ltd. All rights reserved.
