An interpretation of the asymmetric induction observed in rhodium-bis(dibenzophosphole) complex catalyzed hydroformylation according to an X-ray molecular structure analysis of an iridium-(2R,3R)-2,3-O-isopropylidene-1,4-bis(5H-dibenzophosphol-5-yl)-2,3-b

An X-ray molecular structure analysis of [(2<I>R</I>, 3<I>R</I>)-2,3-<I>O</I>-isopropylidene-1,4-bis(5<I>H</I>-dibenzophosphol-5-yl)-2,3-butanediol((−)-DIPHOL)](1,5-cyclooctadiene)chloroiridium(I) was carried out. The complex takes a distorted trigonal bipyramidal structure, and the chelate ring of (−)-DIPHOL makes a chair form, which decreases the distances of atoms in the chelate ring from the P–Ir–P coordination plane. Thus, the chiral coordination structure of DIPHOL becomes remarkably different from that of DIOP. Through a comparison of the results of X-ray analyses, the results obtained in asymmetric hydroformylation (predominant absolute configuration and optical yield of products) catalyzed by the rhodium-complexes were explained on the basis of some well-grounded assumptions.
