Enantioselective addition of various aryllithium reagents to aromatic imines was catalyzed (20 mol‐%) by readily accessible 1,2‐diamines to afford a wide range of protected diarylmethylamines in up to 94 % enantiomeric excess. Furthermore, the absolute configuration of these arylation products was determined by using X‐ray crystallography. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
