Abstract: Method for producing tertiary phosphines by reacting a compound of the general formula (I) in which A is R 1 or L 2 , B is R 2 or L 3 , the R 1 and R 2 radicals are each independently an organic radical having in each case from 1 to 30 carbon atoms, where the R 1 and R 2 radicals may also be joined together; and the leaving groups L 1 to L 3 are each independently halogen, alkyloxy having from 1 to 10 carbon atoms or aryloxy having from 6 to 10 carbon atoms (a) with an alkali metal in an organic aprotic solvent and (b) a compound of the general formula (II) L 4 -R 3 (II) in which the R 3 radical is an organic radical having in each case from 1 to 30 carbon atoms; and the leaving group L 4 is halogen, alkyloxy having from 1 to 10 carbon atoms or aryloxy having from 6 to 10 carbon atoms, in which the resulting reaction mixture is hydrolyzed with an aqueous base which has a pH of >= 10 and the organic phase is removed from the aqueous phase.
