(1<I>S</I>,2<I>S</I>)-1,2-Bis(diphenylphosphinoxy)cyclohexane, (1<I>S</I>,2<I>S</I>)-1,2-bis(phosphinomethyl)cyclohexanes, (2<I>R</I>,3<I>R</I>)-2,3-<I>O</I>-isopropylidene-2,3-dihydroxy-1,4-bis(phosphino) butanes, and (1<I>R</I>,2<I>R</I>)-1,2-bis(phosphinomethyl) cyclobutanes, whose phosphino groups were diphenylphosphino or 5<I>H</I>-dibenzophosphol-5-yl groups where the rotation of phenyl-P bonds is impossible, were used as chiral ligands in rhodium-catalyzed asymmetric hydroformylation. The highest stereoselectivity was attained by the use of (1<I>R</I>,2<I>R</I>)-1,2-bis(5<I>H</I>-dibenzophosphol-5-ylmethyl)cyclobutane or (2<I>R</I>,3<I>R</I>)-2,3-<I>O</I>-isopropylidene-2,3-dihydroxy-1,4-bis(5<I>H</I>-dibenzophosphol-5-yl)butane.
