摘要：

Chiral Ru-BINAP, Rh-DIOP and Rh-BPPM complexes have been physically entrapped in sol-gel matrices. The resulting materials are recyclable leach-proof catalysts for enantioselective hydrogenation of itaconic acid. Chiral methylsuccinic acid of o.p. up to 78% is obtained. The complexes, including the water insoluble Ru-BINAP derivatives, react both in organic and in aqueous media. (C) 1999 Elsevier Science B.V. All rights reserved.
