摘要：

Rhodium complex with a chiral phosphine ligand was intercalated into sodium hectorite by cation exchange method. The intercalation compound was characterized by FT-IR, XRD and TEM measurements. The basal spacing of the compound was estimated to be 2.29 rim from XRD measurement. This novel heterogenized catalyst exhibited a characteristic chiral as well as size recognition of the substrates in the hydrogenation of itaconates. (C) 1999 Elsevier Science B.V.
