Abstract: Ruthenium-alkylidene complexes are obtained by reacting ruthenium (III) compounds with neutral donor ligands in presence of hydrogen and a reducing agent, and then reacting the unisolated intermediate with an acetylene compound in presence of hydrogen. A process for the production of ruthenium complexes of formula RuX2(=CH-CH2R)L L (I), in which X = a monodentate anionic ligand; R = hydrogen or optionally substituted 1-20C alkyl or 6-20C aryl; L , L = neutral electron-donor ligands , comprises (a) reacting RuX3 with L and L in an inert solvent in presence of hydrogen and a reducing agent and then, without isolating intermediates, (b) reacting with compounds of formula R-C?=CH (II) in the presence of hydrogen.

Abstract: Production of propene and 1-butene comprises reading 2-pentene with ethene in the presence of a metathesis catalyst containing a VIb, VIIb or VIIIb metal. An apparatus for carrying out the process is also claimed comprising a metathesis reactor (R1) to react 1-butene with 2-butene, connected to a distillation column (D1) to separate 2-3C light boiling, 4C middle boiling and 5C high boiling phases. The light boiling outlet loads to a column (D3) for separating ethene and propene, the middle boiling outlet leads to the reactor (R1) or is discharged, and the high boiling outlet leads to a reactor (R2) for reacting 2-pentene with ethene, whose outlet leads into a column (D1). The ethene outlet from the column (D3) and an ethene feed are led to the reactor (R2).

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.
