The nature of the group strongly influences the catalytic performance of the metal complexes. The rhodium and ruthenium Me- BIE catalysts are highly effective for the hydrogenation of various C=, C=C and C=N bonds and several synthetically useful CC coupling reactions. 1. u catalyzed asymmetric hydrogenation of $-keto esters, $-keto sulfones and "-keto amides.. u and Ir catalyzed dynamic kinetic resolution for the synthesis of $-hydroxy-"-amino acid derivatives. 3. u catalyzed hydrogenation of C=C bonds, especially ",$-unsaturated acids, allylic alcohols and with other activated groups. 4. Ir catalyzed enantioselective hydrogenation of heteroaromatic compounds. 5. Various asymmetric C-C coupling reactions such as h catalyzed reductive coupling of acetylene to aldehydes and "-ketoesters, t catalyzed intramolecular hydroarylation of unactivated alkenes with indoles and glyoxylate-ene reaction or the d catalyzed enantioselective eck reaction of p-xc64tf (X = Me,, CMe) with dihydrofuran.
