摘要: The invention relates to novel bisphosphonates and to processes for their preparation and for their resolution into the enantiomers. The bisphosphonates according to the invention are valuable intermediates for the preparation of bisphosphine compounds, especially chiral bisphosphine ligands. These in turn are constituents of transition metal complexes which are used as catalysts inter alia in asymmetric hydrogenation. The novel bisphosphonates have the general formula (I) ##STR1## in which R.sup.1 is linear or branched alkyl having up to 6 carbon atoms, aryl or aralkyl, each of which can optionally be substituted, or two radicals R.sup.1 together are a bridging hydrocarbon radical having up to 6 carbon atoms, and can exist in the form of their racemates or as enantiomers.

摘要: The present invention relates to ligands and catalyst systems for the hydroformylation of short and long chain olefins, preferably for the hydroformylation of ally alcohol producing 4-hydroxybutyraldehyde. The ligands disclosed herein are all-trans phosphinomethyl-cyclobutane ligands, such as, for example, all-trans-1,2,3,4-tetra[bis-(3,5-xylyl)phosphinomethyl]-cyclobutane. The catalyst systems comprise these all-trans phosphinomethyl-cyclobutane ligands in combination with an organometallic rhodium complex such as, e.g., (acctylacetonato)-dicarbonyl-rhodium (I). The ligands and catalyst systems of the present invention may be employed in the hydroformylation of olefins, in particular in the hydroformylation of allylalcohol, and provide improved selectivity and high reaction yields. wherein R1 is alkyl, preferably methyl, ethyl or propyl, R2 is H or an alkoxy group, R3 and R4, independently of one another, CH2OR1, CH2O-aralkyl, CH2OH,CH2—[P(3,5-R1,R1-4-R2-phenyl)2] or CH2O—(CH2—CH2—O)m—H (with m being an integer between 1 and 1.000).
