  摘要：

  The enantiopure bidentate indenyl-phosphine ligands (1S)-[2-(3H-inden-1-yl)-1-phenylethyl] diphenylphosphine (9) and [(2R)-2-cyclohexyl-2-(3H-inden-1-yl)ethyl]diphenylphosphine (18) were synthesized in 20% yield and three steps from (R)-styrene oxide and in 61% yield and four steps from vinylcyclohexane, respectively. In both cases ring opening of a spirocyclopropane-1,1'-indene with potassium diphenylphosphide was a key step. Addition of the lithium salts of 9 and 18 to [Rh(mu -Cl)(CO)(2)](2) gave (eta (5):eta (1)-indenyl-CH2CH(Ph)PPh2)RhCO and (eta (5):eta (1)-indenyl-CH(Cy)CH2PPh2)RhCO as 75:25 and 78:22 mixtures of diastereoisomers, from which the major complexes were readily obtained by crystallization. The chiral centers in the linking chain beta and alpha to the indenyl ring had thus induced good planar chirality of the complexed indenyl moiety. Both complexes were characterized by X-ray crystallography.
