A chiral imidazolinium salt with two bulky carbohydrate subunits, N , N ′‐1,3‐bis(methyl 4,6‐ O ‐benzylidene‐3‐deoxy‐α‐ D ‐altropyrano‐3‐yl)imidazolinium chloride ( 4 ), was synthesized in high yield. Deprotonation of 4 with sodium tert ‐butoxide in the presence of [RhCl(COD)] 2 produced NHC‐coordinated rhodium complex 5 along with water adduct 6 to a lesser extent depending on the moisture content of the reaction mixture. These compounds were fully characterized by IR, MS, and 1 H and 13 C{ 1 H} NMR spectroscopy.(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
