A number of chiral 1,2 1,3 and 1,4-diphosphines have been investigated as ligands for the rhodium catalyzed hydrogen transfer from formic acid and its salts to acrylic substrates. The results reveal a strong dependence of the activity and selectivity of the catalytic system on the size of the chelate ring and rigidity of the ligand, the reaction medium, as well as the nature of the substrate.
