    Abstract: The invention relates to a process for L-Iditol by hydrogenating L-Sorbose. Further, the invention also relates to a use of a transition metal complex as hydrogenation catalyst for L-Sorbose. The invention relates to a process for the preparation of L-Iditol comprising at least one reaction step, in which a composition comprising L-Sorbose and hydrogen is reacted in the presence of a transition metal catalyst complex in a homogeneous solution, wherein the transition metal catalyst complex comprises at least one chiral ligand containing at least one phosphorus atom, which is capable of coordinating to the transition metal, and wherein the transition metal is selected from metals of groups 8, 9 and 10 of the periodic table of the elements according to IUPAC. The invention further relates to a use of a transition metal complex as defined above and below as hydrogenation catalyst for compositions comprising L-Iditol or mixtures thereof.

    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 R 1 are identical or different and are each an organic radical having from 1 to 40 carbon atoms, and R 2 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.
