Aryl bromides were first treated with BuLi, and the resulting aryllithium reagents were mixed with titanium tetraisopropoxide and magnesium bromide. The reaction of aldehydes with the resulting mixed titanium reagents, in the presence of 3-(3,5-diphenylphenyl)-H 8 -BINOL (2 mol-%) and titanium

• Novel Axially Chiral Phosphine Ligand with a Fluoro Alcohol Moiety for Rh-Catalyzed Asymmetric Arylation of Aromatic Aldehydes

  A new chiral phosphine ligand (R)-1 possessing a fluoroalcohol moiety was prepared. The (R)-1-coordinated Rh(I) complex showed an excellent catalytic activity for asymmetric 1,2-addition of arylboronic acids to aldehydes to afford highly enantioenriched diarylmethanols. The fluoroalcohol moiety in ligand (R)-1 plays a pivotal role for the high enantioselectivity of the present Rh(I)-catalyzed transformation.
• Aryl Bromides as Inexpensive Starting Materials in the Catalytic Enantioselective Arylation of Aryl Aldehydes: The Additive TMEDA Enhances the Enantioselectivity

  We used aryl bromides as inexpensive starting materials to enantioselectively arylate aldehydes in one pot. Aryl bromides readily transfer aryls to aryllithiums with n-butyllithium, successively to triarylaluminums with aluminum chloride, and then to aryltitaniums with titanium isopropoxide. Finally aryltitaniums arylate aldehydes catalyzed by (S)-H-8-BINOLTi(Oi-Pr)(2) in excellent yields and enantioselectivities. The additive TMEDA evidently suppresses the racemic background reaction promoted by LiCl generated from salt metathesis. This procedure represents a cost-effective and operationally convenient method for enantioenriched diarylmethanols.

  Cheap, energy‐saving, and applicable: With the aid of AlCl3 and BDMAEE [2,2′‐oxybis(N,N‐dimethylethanamine)], a highly asymmetric catalytic addition of various aryl Grignard reagents to aldehydes was achieved under mild conditions with easily prepared (S)‐H8‐BINOL and inexpensive commercially available Ti(OiPr)4 (see scheme), and the reaction could be easily scaled up with no loss of yield and enantioselectivity
