Abstract: The present invention relates to the use of a transition metal catalyst TMC1, which comprises a transition metal M selected from metals of groups 7, 8, 9 and 10 of the periodic table of elements according to IUPAC and a tetradentate ligand of formula I wherein R1 are identical or different and are each an organic radical having from 1 to 40 carbon atoms, and R2 are identical or different and are each an organic radical having from 1 to 40 carbon atoms, as catalyst in processes for formation of compounds comprising at least one carboxylic acid ester functional group —O—C(═O)— starting from at least one primary alcohol and/or hydrogenation of compounds comprising at least one carboxylic acid ester functional group —O—C(═O)—. The present invention further relates to a process for hydrogenation of a compound comprising at least one carboxylic acid ester functional group —O—C(═O)—, to a process for the formation of a compound comprising at least one carboxylic acid ester functional group —O—C(═O)— by dehydrogenase coupling of at least one primary alcohol with a second alcoholic OH-group, to a transition metal complex comprising the tetradentate ligand of formula I and to a process for preparing said transition metal complex.

Abstract: A hydroformylation process for preparing 3,5,5-trimethylhexanal comprising reacting 2,4,4-trimethylpent-2-ene with H2 and CO in a reaction zone in the presence of one or more free organophosphite ligands of the general formula (I) wherein R1, R2, R3, R4 and R5 are each independently H, C1- to C9-alkyl or C1- to C9-alkoxy and R1, R2, R3, R4 and R5 are not H at the same time, and R6, R7, R8, R° and R1° are each independently H, C1- to C9-alkyl or C1- to C9-alkoxy and Re, R7, R8, R° and R1° are not H at the same time, and R11, R12, R13, R14 and R15 are each independently H, C1- to C9-alkyl or C1- to C9-alkoxy and R11, R12, R13, R14 and R15 are not H at the same time, and a homogeneous rhodium catalyst complexed with one or more organophosphite ligands of the general formula (I) at a pressure of 1 to 100 bar abs and a temperature of from 50 to 200° C.

Abstract: Method for hydrogenating an ester with molecular hydrogen to the corresponding alcohols in the presence of a ruthenium complex (I), wherein said complex comprises a tridentate ligand L of the general formula (II)




n and m are each independently 0 or 1, and the solid-dashed double lines represent a single or double bond, with the proviso that in the case of n=1 both solid-dashed double lines represent a single bond and m is 1, and in the case of n=0 one solid-dashed double line represents a single bond and the other solid-dashed double line represents a double bond, wherein in the case of a double bond on the side facing the phenyl ring m=1, in the case of a double bond on the side facing the pyridyl ring m=0, or both solid-dashed double lines represent a single bond and m is 1.
