Highly Enantioselective Hydrophosphonylation of Aldehydes Catalyzed by Tridentate Schiff Base Aluminum(III) Complexes

Abstract

Active in dimeric form: A tridentate Schiff base aluminum(III) complex has been applied in the asymmetric hydrophosphonylation of various aldehydes, giving the corresponding products in good yields with good to excellent ee values (up to 97 %). The strong positive nonlinear effect, along with high-resolution MS analyses, indicates that the reaction is performed in the presence of a dimeric aluminum species. Ad=adamantyl.
