Abstract
Reaction of (rac)-3,3′-bis(methoxymethyl)-BINOL [H 2(CH3OCH2)2BINO] with excess Ti(OiPr)4 and one equivalent of H2O in CH 2Cl2 affords a trinuclear titanium(IV) complex [{(CH 3OCH2)2BINO}Ti3(μ3-O) (OiPr)6(μ2-OiPr)2]. By dissolving it in dichloromethane and hexane and cooling to 0 °C, plate-like pale yellow single crystals (monoclinic, P21/n, a = 12.605(3), b = 21.994(5), c = 19.090(4) Å, β = 92.764(8)°, V = 5286.2(19) Å3, T = 293(2) K) were obtained. Each oxygen atom at 2 or 2′ position of the (CH3OCH2)2BINO ligand bonds to only one titanium atom. There is no interaction between the third Ti atom and the two oxygen atoms of 3,3′-bis(methoxymethyl)-BINOLate.
