METHOD FOR REDUCTION OF ORGANIC MOLECULES

A method for the reduction organic molecules comprising a Ruthenium-Triphosphine complex with aromatic ligands at the phosphors which are ortho or meta substituted.

METHOD FOR PRODUCING TERTIARY PHOSPHINES

The invention relates to a method for producing tertiary phosphines by reacting a compound of general formula (I) with (a) an alkali metal in an organic aprotic solvent and (b) a compound of general formula (II). In formula (I), A represents R1 or L2, B represents R2 or L3, where the groups R1 and R2 independently of one another stand for an organic group with respectively between 1 and 30 carbon atoms and said groups R1 and R2 can also be bonded together. The leaving groups L1 to L3 independently of one another represent halogen, alkyloxy with between 1 and 10 carbon atoms or aryloxy with between 6 and 10 carbon atoms. In formula (II), the group R3 represents an organic group with respectively between 1 and 30 carbon atoms and the leaving group L4 represents halogen, alkyloxy with between 1 and 10 carbon atoms or aryloxy with between 6 and 10 carbon atoms. The reaction mixture that is obtained is hydrolysed using an aqueous base with a pH value of > 10 and the organic phase is then separated from the aqueous phase.
