Abstract: The present invention relates to a method for the production of cyclopentene-oligomer mixtures of formula (I), characterized in that a hydrocarbon mixture containing acyclic monoolefins from an oil refining cracking process (C5-cut) and cyclopentene are transformed in a homogenous or heterogeneous catalyzed metathesis reaction. The invention also relates to cyclopentene oligomers of formula (I) which can be obtained according to said method, and the use thereof.

Abstract: The novel feature in carboxylic acid prodn. from olefins and CO in presence of water at 30-200 degrees C/30-200 bar is that the halogen-free catalyst system comprises a mixt. of (A) Rh (or Rh cpd.) and (B) an N-contg. heterocyclic cpd.

Abstract: The invention relates to a method for producing carboxylic acids or their esters from olefins and carbon monoxide in the presence of water or alcohols at temperatures of between 100 and 270 DEG C and pressure of between 30 and 100 bar. Said method is characterized in that as halogen-free catalyst system it uses a mixture of a) nickel or a nickel compound; b) at least one of the metals of a group including chromium, molybdenum, wolfram, rhenium, ruthenium, osmium, rhodium, iridium, palladium, platinum, silver and gold, or a compound of these metals; c) at least one non-metallic compound from the group of tertiary or quaternary nitrogen, phosphorus or arsenic compounds and nitrogen-containing heterocyclic compounds.

Abstract: The invention concerns a process for carbonylating olefins with carbon monoxide in the presence of water, an alcohol or a carboxylic acid and a halogen-free catalyst. Nickel or a nickel compound and at least one of the metals from the group comprising chromium, molybdenum, tungsten, rhenium, ruthenium, osmium, rhodium, iridium, palladium, platinum, silver and gold or a combination of these metals is used as the catalyst.

Abstract: The proposed production of 1,6-hexane diol involves the following steps: a) epoxybutadiene is reacted in the presence of a metathesis catalyst, ethene being broken down to bisepoxihexatrienes of formulae (Ia) and (Ib); and b) these bisepoxihexatrienes are then hydrated with hydrogen to form 1,6-hexane diol.

Abstract: A method (a) of preparing butyrolactones of formula (I) comprises reacting an alkyne of formula R -C?=C-R (II) with CO and H2 or H2 formed in situ at elevated pressure and temp. in the presence of a transition metal catalyst. R , R = H, (hydroxy)alkyl or trialkylsilyl or aryl gps., opt. with inert substits. Also claimed is a second method (b) of preparing the corresp. 2-(5H)-furanones of formula (III) which comprises reacting (II) with CO and H2 gas in the presence of transition metal catalysts and amine bases at 60-140 deg C and a H2 partial pressure of > 50 bar. (III) may then be hydrogenated to (I) in a separate hydrogenation reaction.
