The invention relates to a process for the production of 1,6-difunctionalized hexane derivatives from 1,3-diunsaturated hydrocarbons, preferably butadiene, wherein a hydroformylation with carbon monoxide and hydrogen is performed in the presence of an at least dihydric alkanol and during the hydroformylation the temperature is increased. The reaction yields the acetals of the 1,6-hexanedial derivatives which are isolated and further reacted to obtain the desired 1,6-difunctionalized hexane derivatives, in particular 1,6-hexanediamine, 1,6-hexanediol and adipic acid.

Hydroformylation process for producing 1,6-disubstituted hexane derivatives

The present invention relates to a method for the regioselective hydroformylation of polyunsaturated acyclic hydrocarbons, which are 1, 3 butadienes, which, in the 2 position, bear a saturated or monounsaturated or polyunsaturated acyclic hydrocarbon radical. The present invention also relates to the production of secondary products of these hydroformylation products, especially of ambrox.

Method for the hydroformylation of 2-substituted butadienes and the production of secondary products thereof, especially ambrox

Pnicogen chelate compounds which have two pnicogen-containing groups joined to one another via a xanthene-like or triptycene-like molecular skeleton and in which at least one pyrrole group is covalently bound via its nitrogen atom to each pnicogen atom form complexes with metals of transition group VIII which are useful as catalysts for the hydroformylation of olefins.

Ligands for pnicogen chelate complexes with a metal of subgroup VIII and use of the complexes as catalysts for hydroformylation, carbonylation, hydrocyanation or hydrogenation

Novel compounds of phosphorus, of arsenic and of antimony can be used as ligands to form complexes of metals of transition group VIII which can be used in catalysts for hydroformylation, hydrocyanation, carbonylation, hydrogenations, oligomerization and polymerization of olefins and for metathesis.
