Synthesis and characterization of new chiral palladium β-diimine complexes

The synthesis and characterization of a range of chiral β-diimine ligands and their complexes with palladium(II) has been investigated. The introduction of chirality can be easily achieved through a combination of both achiral and chiral building blocks.

Efficient preparation of optically pure C2-symmetrical cyclic amines for chiral auxiliary

Optically pure C2-symmetrical amines were efficiently synthesized from the corresponding diols obtained from the enantioselective borohydride reduction of the diketones catalyzed by the optically active β-ketoiminato cobalt(II) complex.

The Mechanism of Asymmetric Hydrogenation. Chiral Bis(diphenylphosphino)-α-phenylalkane Complexes in Catalytic and Structural Studies

(R)-1,2-Bis(diphenylphosphino)phenylethane has been synthesised in good overall yield from (S)-mandelic acid ; its cationic rhodium(I) solvated complex has been shown to be effective in catalytic asymmetric hydrogenation with optical yields of up to 88percent having been observed.The n.m.r. spectra of complexes of this phosphine are discussed.Racemic (R*,R*)-1,3-bis(diphenylphosphino)-1,3-diphenylpropane and (R*,R*)-1,4-bis(diphenylphosphino)-1,4-diphenylbutane have been prepared.These form a range of rhodium complexes with dehydroamino-acids whose structures may be assigned on the basis of characteristic n.m.r.P-Rh and P-P coupling constants.
