Abstract: Symmetrical or asymmetrical bis-phosphino, bis-arsino or phosphino-arsino compounds are produced by reacting a dihalo-organic compound with two benzyl-diorganyl-phosphine or -arsine compounds which may or may not be identical and then hydrogenating the product. A process for the production of compounds of formula (V) involves reaction of a compound of formula (I) with a dihalo compound (II) and a compound of formula (III) followed by hydrogenation. Hal-X-Hal (II) R R E-X-ER R (V) E = phosphorus or arsenic; X = a bridging group with 1-10 atoms between the atoms of E; R , R , R , R = 1-20C alkyl, 3-10C cycloalkyl, aryl or heteroaryl with up to 4 condensed rings, or 7-20C aralkyl (all optionally substituted), or R , R and/or R , R together may form 2-20C alkylene, arylene or heteroarylene groups with up to 4 condensed rings, or 7-20C aralkylene (all optionally substituted; R -R = H, hydroxyl, halogen, acyl, CHO, 1-12C alkyl or 6-12C aryl, with the proviso that R and R are not both OH; Hal = F, Cl, Br or I; R -R = as defined for R -R .

Abstract: The invention relates to ruthenium complexes of the general formulas (I) RuX2(=CH-CH2R)L1L2 or (IV) RuXY(=CH-CH2R)L1L2, where X, Y are anionic ligands, R is hydrogen or a possibly substituted C1-C20 alkyl rest or C6-C20 aryl rest, and L1 and L2 independently of each other are neutral electron donor ligands. Said ruthenium complexes are produced by (a) reacting RuX3 with L1 and L2 in an inert solvent in the presence of a reducing agent and hydrogen, and (b) by reacting the resulting product with compounds of the general formula (II) RCCH, where R has the meaning given above, possibly in the presence of water and possibly after isolation of the intermediate stage with HY, (HL1)Y or (HL2)Y.

Abstract: A process for the production of bisphosphino- and bisarsino-compounds comprises reaction of an aryl phosphorous or arsenic containing compound with a dihalogenated compound. A process for the production of compounds of formula (5) comprises reaction of a compound of formula (1) with a dihalo compound of formula (2) and a compound of formula (3) followed by hydrogenation. Hal - X - Hal (2) R R - E - X - E - R - R (5) E = P, As; X = a divalent bridging group whereby are separated by 1-10 atoms; R , R , R , R =1-20C alkyl, 3-10C (cycloalkyl, aryl or heteroaryl having up to 4 condensed aromatic rings or 7-20C aralkyl, optionally substituted or R , R and/or R , R together are 2-20C alkylene, arylene or heteroarylene with up to 4 aromatic rings, 7-20C aralalkylene, optionally substituted; R , R R , R , R , R = H, OH, halogen, acyl, CHO, 1-12C alkyl, 6-12C aryl whereby R and R are not both OH; Hal = F, Cl, Br or I.

Abstract: The invention relates to a method of producing ruthenium complexes of general formula (I): RuX2(=CH-CH2R)L L , wherein X is an anionic ligand, R is hydrogen or an optionally substituted C1-20 alkyl radical or C6-20 aryl radical, and L and L independently are neutral electron-donor ligands. Said ruthenium complexes are produced by a) reacting RuX3 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 and L 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.

Abstract: 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 C1-20-alkyl, C6-20-aryl or C7-2 0- alkylaryl radicals; and L1, L2 independently represent neutral electron dono r 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.
