4 -containing hydrocarbon mixtures, comprising isobutene and 1-butene, by hydroformylation, wherein the catalytic system used is made of one of the transition metals of the group 8 to 10, preferably rhodium, and a bisphosphite ligand of the formula (I), where X is a divalent substituted or unsubstituted bisalkylene or bisarylene group having one or more heteroatom(s), Y is a divalent substituted or unsubstituted bisarylene or bisalkylene group having one or more heteroatom(s), Z is oxygen or NR
9 , and R
1 , R
2 , R
3 , R
4 are identical or different, substituted or unsubstituted, linked, unlinked or condensed aryl or heteroaryl groups, and R
9 is hydrogen or a substituted or unsubstituted alkyl or aryl group having one or more heteroatom(s), wherein the bisphosphite ligand of the formula (I) is used in an excess of a molar ratio of 100:1 to 1:1 to the transition metal, and that with a 1-butene conversion of more than 95% less than 5% of the present isobutene is reacted.method for separating 1–butene from c

摘要： The invention relates to a method for producing organophosphites, organophosphonites and organophosphinites by the condensation of phosphorus trihalides or organophosphorus halides with organic compounds that carry hydroxy groups, in the presence of polymeric alkaline ion-exchange resins. The inventive method permits the production of trivalent organophosphorus compounds, which can be used e.g. as ligands in rhodium complexes that can be utilised as a catalyst in hydroformylation.
