Significance The authors have developed the atom-economical, mixed aluminum reagents AlArEt 2 (THF) for the arylation to both aldehydes and ketones. The resulting secondary and tertiary alcohols were obtained in high yields and enantioselectivities. In addition, the aluminum reagents were easily prepared from the reactions of either AlEt 2 Br(THF) with ArMgBr or AlAr 3 (THF) with AlEt 3 (THF).
