  • Patent number: 5789624
    Abstract: Hydroformylation of alkenes to aldehydes in the presence of a rhodium complex catalyst is improved by the addition of a novel bidentate ligand of the formula ##STR1## wherein R.sub.1, R.sub.2, R.sub.1 ' and R.sub.2 ' are organic radicals selected from alicyclic, aliphatic and aromatic groups of which at least one is preferably substituted with at least one electronegative moiety and the methylene groups are present at the trans-2,3 positions on the norbomane moiety. The invention also provides a novel method for producing the bidentate ligand and novel intermediate phosphine oxide and phosphinous acid compounds.
