Summary: Preparatiion of the chiral nitrogen ligands will be performed, and their complexes with Rh(I), Cu(II), and some other metals will be isolated and characterized. Structure and conformation of the complexes in solution will be studied by NMR and CD, whereas in some cases solid state structure will be determined by X-ray. Catalytic efficacy of organometallic complexes with chiral nitrogen ligands will be studied for some selected reactions, as are cyclopropanation, transfer hydrogenation, and hydrogenation with dyhydrogen.

Keywords: Stereoselective homogeneous catalysis, organometallic catalytic complexes, chiral nitrogen bases, hydrogenation, hydrogen transfer, cyclopropanation

Research goals: The main targets of the proposed research are: a. Synthesis of new chiral ligands with nitrogen as the donor heteroatom, both of C1 and C2 symmetry, and preparation of their homogeneous catalytic complexes with Rh(I), Rh(II), and Cu(II) ions, which will be examined in enantioselective hydrogenation, hydrogen transfer, and cyclopropanation. b. Detailed knowledge of the mechanism of hydrogenation with molecular hydrogen, catalyzed by Rh(I) complexes of bidentate nitrogen ligands. It is expected that the proposed research will broaden our knowledge of correlation between structural and conformational properties of chiral ligands in catalytically active complexes, and degree of their enantioselectivity. Successful application of some catalysts in solving some technical problems-enantioselective synthesis of biologically or commercially interesting compounds is expected.
