英文摘要: Abstract(#br)The optically active indenyl-linked phosphane ligands ( S )-[2-(3 H -inden-1-yl)-1-phenylethyl]diphenylphosphane ( L 1 ) and ( S )-[2-(4,7-dimethyl-3 H -inden-1-yl)-1-phenyl-ethyl]diphenylphosphane ( L 2 ) were synthesized in three steps from ( R )-1-phenylethane-1,2-diol in excellent yields. Their lithium salts reacted with [Rh(μ-Cl)(η 2 -CH 2 CH 2 ) 2 ] 2 at −78°C in THF affording the planar chiral complexes ( S , R pl + S pl )-[Rh(η 5 -indenyl-CH 2 CH(Ph)PPh 2 - kP )(η 2 -CH 2 CH 2 )] and ( S , R pl + S pl )-[Rh(η 5 -4,7-dimethylindenyl-CH 2 CH(Ph)PPh 2 - kP )(η 2 -CH 2 CH 2 )] as 61:39 and 15:85 mixtures of diastereomers. The complexes were isolated in optically pure form by...
