The nonracemic bis(indene) (+)-(1R,2R,4R,5R)-1,4-bis(3‘-indenyl)-2,5-diisopropylcyclohexane (10) was synthesized in 60% yield from the addition of indenyllithium to the corresponding bis(methanesulfonate) ester of 2,4-diisopropyl-1,4-cyclohexanediol. Deprotonation of bis(indene) 10 with n-BuLi followed by metalation with TiCl3 and oxidative workup (HCl, air, chloroform) gave the single stereoisomeric 2,5-diisopropylcyclohexane-1,4-diyl-bridged bis(indenyl)titanium dichloride 3 in 80% yield. Attempts to form the corresponding bis(indenyl)zirconium dichloride were unsuccessful. Catalytic hydrogenation of bis(indenyl)titanium dichloride 3 gave the 2,5-diisopropylcyclohexane-1,4-diyl-bridged bis(tetrahydroindenyl)titanium dichloride 4 in 76% yield. The solid-state structure of 4 was determined by X-ray crystallographic methods. Nonracemic mixtures of chiral bis(indenyl)titanium dichloride 3 and bis(tetrahydroindenyl)titanium dichloride 4 were examined as catalysts for the pinacol coupling of benzaldehyde in t...
