    摘要: In ruthenium complexes of general formula A or B, X1, X2 independently represent single or multidentate anionic ligands; R, R', R'' independently represent hydrogen or optionally substituted C¿1-20?-alkyl, C6-20-aryl or C7-20-alkylaryl radicals; and L?1, L2¿ independently represent neutral electron donor ligands which are co-ordinated at the metallic centre as carboids, and which can be linked by a bridge W having 0 to 20 carbon atoms. Said bridge can be a constituent of a cyclic or aromatic group and can be split by heteroatoms, with the exception of C,N-heterocyclic five-membered ring systems.

    摘要: The invention relates to a method for selectively producing 3-alkene acid esters by adding alkyl formates to dienes according to general reaction formula (I), wherein R1 to R6 independently from one another are hydrogen or C1-C30-alkyl, C6-C30-aryl, C7-C30-alkylaryl, C5-C12-cycloalkyl or C1-C21-alkyl-C6-C9-cycloalkyl and R7 is a C1-C30-alkyl radical, in the presence of CO with a partial pressure of at least 10 bar (1 MPa), using a catalyst containing a Pd-compound and one or more compounds of the MCln-type, whereby M has one of the following meanings: an alkaline earth metall ion with n = 2, a metallic ion of the fourth group (IV. subgroup) with n = 4, a metallic ion of the sixth group (VI. subgroup) with n = 3, 5 or 6, in the absence of an organic base containing phosphor or nitrogen.

    摘要: The invention relates to a method of producing ruthenium complexes of general formula (I): RuX2(=CH-CH2R)L1L2, wherein X is an anionic ligand, R is hydrogen or an optionally substituted C¿1-20? alkyl radical or C6-20 aryl radical, and L?1 and L2¿ independently are neutral electron-donor ligands. Said ruthenium complexes are produced by a) reacting RuX¿3? with a diene in a solvent on the basis of one or several aliphatic secondary alcohols in the presence of a reducing adjuvant, reacting said mixture with L?1 and L2¿ in the presence of at least one coordinating weak base and hydrogen and without isolating any intermediates, b) reacting the mixture with compounds of general formula (II): R-C≡CH, wherein R has the meaning indicated above, in the presence of a soluble chloride source.
