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: The invention relates to a method for producing 1,6-hexanediol having a puri ty of > 99.5 wt. % by catalytic dimerisation of acrylic acid esters, catalyt ic hydrogenation of the thus obtained hexene diacidic diester in order to form 1.6-hexanediol. Said method consists in: a) dimerising C1- C8-acrylic acid esters in the presence of at least one rhodium compound in order to form mixtures predominantly of 2- and 3-hexene diacdic diesters, b) hydrating the obtained dimerisation discharge in the presence of chrome-free catalysts containing mainly copper as a hydrogenation component and c) purifying the thus obtained raw 1.6-hexanediol by fractionating distillation.
