Résumé

The stereoselective synthesis of new phospholylmethano P-chirogenic-phosphine-borane was achieved by P-C bond formation of the bridge, using electrophilic or nucleophilic P*-building blocks. These (PCH2P2)-C-1*.BH3 ligands behaved as chelating (kappa(1)-P-1)-(eta(2) -BH3) entities towards the cationic rhodium(I) centre. The resulting chiral rhodium complexes were tested in asymmetric rhodium catalyzed hydrogenation of methyl 2-(acetamido)acrylate. (C) 2021 Elsevier B.V. All rights reserved.
